+[![NPM version](https://img.shields.io/npm/v/argparse.svg)](https://www.npmjs.org/package/argparse)
+
+CLI arguments parser for node.js. Javascript port of python's
+[argparse](http://docs.python.org/dev/library/argparse.html) module
+(original version 3.2). That's a full port, except some very rare options,
+recorded in issue tracker.
+
+**NB. Difference with original.**
+
+- Method names changed to camelCase. See [generated docs](http://nodeca.github.com/argparse/).
+- Use `defaultValue` instead of `default`.
+- Use `argparse.Const.REMAINDER` instead of `argparse.REMAINDER`, and
+  similarly for constant values `OPTIONAL`, `ZERO_OR_MORE`, and `ONE_OR_MORE`
+  (aliases for `nargs` values `'?'`, `'*'`, `'+'`, respectively), and
+  `SUPPRESS`.
+
+
+Example
+=======
+
+test.js file:
+
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse example'
+});
+parser.addArgument(
+  [ '-f', '--foo' ],
+  {
+    help: 'foo bar'
+  }
+);
+parser.addArgument(
+  [ '-b', '--bar' ],
+  {
+    help: 'bar foo'
+  }
+);
+parser.addArgument(
+  '--baz',
+  {
+    help: 'baz bar'
+  }
+);
+var args = parser.parseArgs();
+console.dir(args);
+```
+
+Display help:
+
+```
+$ ./test.js -h
+usage: example.js [-h] [-v] [-f FOO] [-b BAR] [--baz BAZ]
+
+Argparse example
+
+Optional arguments:
+  -h, --help         Show this help message and exit.
+  -v, --version      Show program's version number and exit.
+  -f FOO, --foo FOO  foo bar
+  -b BAR, --bar BAR  bar foo
+  --baz BAZ          baz bar
+```
+
+Parse arguments:
+
+```
+$ ./test.js -f=3 --bar=4 --baz 5
+{ foo: '3', bar: '4', baz: '5' }
+```
+
+More [examples](https://github.com/nodeca/argparse/tree/master/examples).
+
+
+ArgumentParser objects
+======================
+
+```
+new ArgumentParser({parameters hash});
+```
+
+Creates a new ArgumentParser object.
+
+**Supported params:**
+
+- ```description``` - Text to display before the argument help.
+- ```epilog``` - Text to display after the argument help.
+- ```addHelp``` - Add a -h/–help option to the parser. (default: true)
+- ```argumentDefault``` - Set the global default value for arguments. (default: null)
+- ```parents``` - A list of ArgumentParser objects whose arguments should also be included.
+- ```prefixChars``` - The set of characters that prefix optional arguments. (default: ‘-‘)
+- ```formatterClass``` - A class for customizing the help output.
+- ```prog``` - The name of the program (default: `path.basename(process.argv[1])`)
+- ```usage``` - The string describing the program usage (default: generated)
+- ```conflictHandler``` - Usually unnecessary, defines strategy for resolving conflicting optionals.
+
+**Not supported yet**
+
+- ```fromfilePrefixChars``` - The set of characters that prefix files from which additional arguments should be read.
+
+
+Details in [original ArgumentParser guide](http://docs.python.org/dev/library/argparse.html#argumentparser-objects)
+
+
+addArgument() method
+====================
+
+```
+ArgumentParser.addArgument(name or flag or [name] or [flags...], {options})
+```
+
+Defines how a single command-line argument should be parsed.
+
+- ```name or flag or [name] or [flags...]``` - Either a positional name
+  (e.g., `'foo'`), a single option (e.g., `'-f'` or `'--foo'`), an array
+  of a single positional name (e.g., `['foo']`), or an array of options
+  (e.g., `['-f', '--foo']`).
+
+Options:
+
+- ```action``` - The basic type of action to be taken when this argument is encountered at the command line.
+- ```nargs```- The number of command-line arguments that should be consumed.
+- ```constant``` - A constant value required by some action and nargs selections.
+- ```defaultValue``` - The value produced if the argument is absent from the command line.
+- ```type``` - The type to which the command-line argument should be converted.
+- ```choices``` - A container of the allowable values for the argument.
+- ```required``` - Whether or not the command-line option may be omitted (optionals only).
+- ```help``` - A brief description of what the argument does.
+- ```metavar``` - A name for the argument in usage messages.
+- ```dest``` - The name of the attribute to be added to the object returned by parseArgs().
+
+Details in [original add_argument guide](http://docs.python.org/dev/library/argparse.html#the-add-argument-method)
+
+
+Action (some details)
+================
+
+ArgumentParser objects associate command-line arguments with actions.
+These actions can do just about anything with the command-line arguments associated
+with them, though most actions simply add an attribute to the object returned by
+parseArgs(). The action keyword argument specifies how the command-line arguments
+should be handled. The supported actions are:
+
+- ```store``` - Just stores the argument’s value. This is the default action.
+- ```storeConst``` - Stores value, specified by the const keyword argument.
+  (Note that the const keyword argument defaults to the rather unhelpful None.)
+  The 'storeConst' action is most commonly used with optional arguments, that
+  specify some sort of flag.
+- ```storeTrue``` and ```storeFalse``` - Stores values True and False
+  respectively. These are special cases of 'storeConst'.
+- ```append``` - Stores a list, and appends each argument value to the list.
+  This is useful to allow an option to be specified multiple times.
+- ```appendConst``` - Stores a list, and appends value, specified by the
+  const keyword argument to the list. (Note, that the const keyword argument defaults
+  is None.) The 'appendConst' action is typically used when multiple arguments need
+  to store constants to the same list.
+- ```count``` - Counts the number of times a keyword argument occurs. For example,
+  used for increasing verbosity levels.
+- ```help``` - Prints a complete help message for all the options in the current
+  parser and then exits. By default a help action is automatically added to the parser.
+  See ArgumentParser for details of how the output is created.
+- ```version``` - Prints version information and exit. Expects a `version=`
+  keyword argument in the addArgument() call.
+
+Details in [original action guide](http://docs.python.org/dev/library/argparse.html#action)
+
+
+Sub-commands
+============
+
+ArgumentParser.addSubparsers()
+
+Many programs split their functionality into a number of sub-commands, for
+example, the svn program can invoke sub-commands like `svn checkout`, `svn update`,
+and `svn commit`. Splitting up functionality this way can be a particularly good
+idea when a program performs several different functions which require different
+kinds of command-line arguments. `ArgumentParser` supports creation of such
+sub-commands with `addSubparsers()` method. The `addSubparsers()` method is
+normally called with no arguments and returns an special action object.
+This object has a single method `addParser()`, which takes a command name and
+any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object
+that can be modified as usual.
+
+Example:
+
+sub_commands.js
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse examples: sub-commands',
+});
+
+var subparsers = parser.addSubparsers({
+  title:'subcommands',
+  dest:"subcommand_name"
+});
+
+var bar = subparsers.addParser('c1', {addHelp:true});
+bar.addArgument(
+  [ '-f', '--foo' ],
+  {
+    action: 'store',
+    help: 'foo3 bar3'
+  }
+);
+var bar = subparsers.addParser(
+  'c2',
+  {aliases:['co'], addHelp:true}
+);
+bar.addArgument(
+  [ '-b', '--bar' ],
+  {
+    action: 'store',
+    type: 'int',
+    help: 'foo3 bar3'
+  }
+);
+
+var args = parser.parseArgs();
+console.dir(args);
+
+```

+JS-YAML - YAML 1.2 parser / writer for JavaScript
+=================================================
+
+[![Build Status](https://travis-ci.org/nodeca/js-yaml.svg?branch=master)](https://travis-ci.org/nodeca/js-yaml)
+[![NPM version](https://img.shields.io/npm/v/js-yaml.svg)](https://www.npmjs.org/package/js-yaml)
+
+__[Online Demo](http://nodeca.github.com/js-yaml/)__
+
+
+This is an implementation of [YAML](http://yaml.org/), a human-friendly data
+serialization language. Started as [PyYAML](http://pyyaml.org/) port, it was
+completely rewritten from scratch. Now it's very fast, and supports 1.2 spec.
+
+
+Installation
+------------
+
+### YAML module for node.js
+
+```
+npm install js-yaml
+```
+
+
+### CLI executable
+
+If you want to inspect your YAML files from CLI, install js-yaml globally:
+
+```
+npm install -g js-yaml
+```
+
+#### Usage
+
+```
+usage: js-yaml [-h] [-v] [-c] [-t] file
+
+Positional arguments:
+  file           File with YAML document(s)
+
+Optional arguments:
+  -h, --help     Show this help message and exit.
+  -v, --version  Show program's version number and exit.
+  -c, --compact  Display errors in compact mode
+  -t, --trace    Show stack trace on error
+```
+
+
+### Bundled YAML library for browsers
+
+``` html
+<!-- esprima required only for !!js/function -->
+<script src="esprima.js"></script>
+<script src="js-yaml.min.js"></script>
+<script type="text/javascript">
+var doc = jsyaml.load('greeting: hello\nname: world');
+</script>
+```
+
+Browser support was done mostly for the online demo. If you find any errors - feel
+free to send pull requests with fixes. Also note, that IE and other old browsers
+needs [es5-shims](https://github.com/kriskowal/es5-shim) to operate.
+
+Notes:
+
+1. We have no resources to support browserified version. Don't expect it to be
+   well tested. Don't expect fast fixes if something goes wrong there.
+2. `!!js/function` in browser bundle will not work by default. If you really need
+   it - load `esprima` parser first (via amd or directly).
+3. `!!bin` in browser will return `Array`, because browsers do not support
+   node.js `Buffer` and adding Buffer shims is completely useless on practice.
+
+
+API
+---
+
+Here we cover the most 'useful' methods. If you need advanced details (creating
+your own tags), see [wiki](https://github.com/nodeca/js-yaml/wiki) and
+[examples](https://github.com/nodeca/js-yaml/tree/master/examples) for more
+info.
+
+``` javascript
+const yaml = require('js-yaml');
+const fs   = require('fs');
+
+// Get document, or throw exception on error
+try {
+  const doc = yaml.safeLoad(fs.readFileSync('/home/ixti/example.yml', 'utf8'));
+  console.log(doc);
+} catch (e) {
+  console.log(e);
+}
+```
+
+
+### safeLoad (string [ , options ])
+
+**Recommended loading way.** Parses `string` as single YAML document. Returns either a
+plain object, a string or `undefined`, or throws `YAMLException` on error. By default, does
+not support regexps, functions and undefined. This method is safe for untrusted data.
+
+options:
+
+- `filename` _(default: null)_ - string to be used as a file path in
+  error/warning messages.
+- `onWarning` _(default: null)_ - function to call on warning messages.
+  Loader will call this function with an instance of `YAMLException` for each warning.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ - specifies a schema to use.
+  - `FAILSAFE_SCHEMA` - only strings, arrays and plain objects:
+    http://www.yaml.org/spec/1.2/spec.html#id2802346
+  - `JSON_SCHEMA` - all JSON-supported types:
+    http://www.yaml.org/spec/1.2/spec.html#id2803231
+  - `CORE_SCHEMA` - same as `JSON_SCHEMA`:
+    http://www.yaml.org/spec/1.2/spec.html#id2804923
+  - `DEFAULT_SAFE_SCHEMA` - all supported YAML types, without unsafe ones
+    (`!!js/undefined`, `!!js/regexp` and `!!js/function`):
+    http://yaml.org/type/
+  - `DEFAULT_FULL_SCHEMA` - all supported YAML types.
+- `json` _(default: false)_ - compatibility with JSON.parse behaviour. If true, then duplicate keys in a mapping will override values rather than throwing an error.
+
+NOTE: This function **does not** understand multi-document sources, it throws
+exception on those.
+
+NOTE: JS-YAML **does not** support schema-specific tag resolution restrictions.
+So, the JSON schema is not as strictly defined in the YAML specification.
+It allows numbers in any notation, use `Null` and `NULL` as `null`, etc.
+The core schema also has no such restrictions. It allows binary notation for integers.
+
+
+### load (string [ , options ])
+
+**Use with care with untrusted sources**. The same as `safeLoad()` but uses
+`DEFAULT_FULL_SCHEMA` by default - adds some JavaScript-specific types:
+`!!js/function`, `!!js/regexp` and `!!js/undefined`. For untrusted sources, you
+must additionally validate object structure to avoid injections:
+
+``` javascript
+const untrusted_code = '"toString": !<tag:yaml.org,2002:js/function> "function (){very_evil_thing();}"';
+
+// I'm just converting that string, what could possibly go wrong?
+require('js-yaml').load(untrusted_code) + ''
+```
+
+
+### safeLoadAll (string [, iterator] [, options ])
+
+Same as `safeLoad()`, but understands multi-document sources. Applies
+`iterator` to each document if specified, or returns array of documents.
+
+``` javascript
+const yaml = require('js-yaml');
+
+yaml.safeLoadAll(data, function (doc) {
+  console.log(doc);
+});
+```
+
+
+### loadAll (string [, iterator] [ , options ])
+
+Same as `safeLoadAll()` but uses `DEFAULT_FULL_SCHEMA` by default.
+
+
+### safeDump (object [ , options ])
+
+Serializes `object` as a YAML document. Uses `DEFAULT_SAFE_SCHEMA`, so it will
+throw an exception if you try to dump regexps or functions. However, you can
+disable exceptions by setting the `skipInvalid` option to `true`.
+
+options:
+
+- `indent` _(default: 2)_ - indentation width to use (in spaces).
+- `noArrayIndent` _(default: false)_ - when true, will not add an indentation level to array elements
+- `skipInvalid` _(default: false)_ - do not throw on invalid types (like function
+  in the safe schema) and skip pairs and single values with such types.
+- `flowLevel` (default: -1) - specifies level of nesting, when to switch from
+  block to flow style for collections. -1 means block style everwhere
+- `styles` - "tag" => "style" map. Each tag may have own set of styles.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ specifies a schema to use.
+- `sortKeys` _(default: `false`)_ - if `true`, sort keys when dumping YAML. If a
+  function, use the function to sort the keys.
+- `lineWidth` _(default: `80`)_ - set max line width.
+- `noRefs` _(default: `false`)_ - if `true`, don't convert duplicate objects into references
+- `noCompatMode` _(default: `false`)_ - if `true` don't try to be compatible with older
+  yaml versions. Currently: don't quote "yes", "no" and so on, as required for YAML 1.1
+- `condenseFlow` _(default: `false`)_ - if `true` flow sequences will be condensed, omitting the space between `a, b`. Eg. `'[a,b]'`, and omitting the space between `key: value` and quoting the key. Eg. `'{"a":b}'` Can be useful when using yaml for pretty URL query params as spaces are %-encoded.
+
+The following table show availlable styles (e.g. "canonical",
+"binary"...) available for each tag (.e.g. !!null, !!int ...). Yaml
+output is shown on the right side after `=>` (default setting) or `->`:
+
+``` none
+!!null
+  "canonical"   -> "~"
+  "lowercase"   => "null"
+  "uppercase"   -> "NULL"
+  "camelcase"   -> "Null"
+
+!!int
+  "binary"      -> "0b1", "0b101010", "0b1110001111010"
+  "octal"       -> "01", "052", "016172"
+  "decimal"     => "1", "42", "7290"
+  "hexadecimal" -> "0x1", "0x2A", "0x1C7A"
+
+!!bool
+  "lowercase"   => "true", "false"
+  "uppercase"   -> "TRUE", "FALSE"
+  "camelcase"   -> "True", "False"
+
+!!float
+  "lowercase"   => ".nan", '.inf'
+  "uppercase"   -> ".NAN", '.INF'
+  "camelcase"   -> ".NaN", '.Inf'
+```
+
+Example:
+
+``` javascript
+safeDump (object, {
+  'styles': {
+    '!!null': 'canonical' // dump null as ~
+  },
+  'sortKeys': true        // sort object keys
+});
+```
+
+### dump (object [ , options ])
+
+Same as `safeDump()` but without limits (uses `DEFAULT_FULL_SCHEMA` by default).
+
+
+Supported YAML types
+--------------------
+
+The list of standard YAML tags and corresponding JavaScipt types. See also
+[YAML tag discussion](http://pyyaml.org/wiki/YAMLTagDiscussion) and
+[YAML types repository](http://yaml.org/type/).
+
+```
+!!null ''                   # null
+!!bool 'yes'                # bool
+!!int '3...'                # number
+!!float '3.14...'           # number
+!!binary '...base64...'     # buffer
+!!timestamp 'YYYY-...'      # date
+!!omap [ ... ]              # array of key-value pairs
+!!pairs [ ... ]             # array or array pairs
+!!set { ... }               # array of objects with given keys and null values
+!!str '...'                 # string
+!!seq [ ... ]               # array
+!!map { ... }               # object
+```
+
+**JavaScript-specific tags**
+
+```
+!!js/regexp /pattern/gim            # RegExp
+!!js/undefined ''                   # Undefined
+!!js/function 'function () {...}'   # Function
+```
+
+Caveats
+-------
+
+Note, that you use arrays or objects as key in JS-YAML. JS does not allow objects
+or arrays as keys, and stringifies (by calling `toString()` method) them at the
+moment of adding them.
+
+``` yaml
+---
+? [ foo, bar ]
+: - baz
+? { foo: bar }
+: - baz
+  - baz
+```
+
+``` javascript
+{ "foo,bar": ["baz"], "[object Object]": ["baz", "baz"] }
+```
+
+Also, reading of properties on implicit block mapping keys is not supported yet.
+So, the following YAML document cannot be loaded.
+
+``` yaml
+&anchor foo:
+  foo: bar
+  *anchor: duplicate key
+  baz: bat
+  *anchor: duplicate key
+```

+/**
+ * `Buffer` objects are used to represent a fixed-length sequence of bytes. Many
+ * Node.js APIs support `Buffer`s.
+ *
+ * The `Buffer` class is a subclass of JavaScript's [`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) class and
+ * extends it with methods that cover additional use cases. Node.js APIs accept
+ * plain [`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array)s wherever `Buffer`s are supported as well.
+ *
+ * The `Buffer` class is within the global scope, making it unlikely that one
+ * would need to ever use `require('buffer').Buffer`.
+ *
+ * ```js
+ * // Creates a zero-filled Buffer of length 10.
+ * const buf1 = Buffer.alloc(10);
+ *
+ * // Creates a Buffer of length 10,
+ * // filled with bytes which all have the value `1`.
+ * const buf2 = Buffer.alloc(10, 1);
+ *
+ * // Creates an uninitialized buffer of length 10.
+ * // This is faster than calling Buffer.alloc() but the returned
+ * // Buffer instance might contain old data that needs to be
+ * // overwritten using fill(), write(), or other functions that fill the Buffer's
+ * // contents.
+ * const buf3 = Buffer.allocUnsafe(10);
+ *
+ * // Creates a Buffer containing the bytes [1, 2, 3].
+ * const buf4 = Buffer.from([1, 2, 3]);
+ *
+ * // Creates a Buffer containing the bytes [1, 1, 1, 1] – the entries
+ * // are all truncated using `(value &#x26; 255)` to fit into the range 0–255.
+ * const buf5 = Buffer.from([257, 257.5, -255, '1']);
+ *
+ * // Creates a Buffer containing the UTF-8-encoded bytes for the string 'tést':
+ * // [0x74, 0xc3, 0xa9, 0x73, 0x74] (in hexadecimal notation)
+ * // [116, 195, 169, 115, 116] (in decimal notation)
+ * const buf6 = Buffer.from('tést');
+ *
+ * // Creates a Buffer containing the Latin-1 bytes [0x74, 0xe9, 0x73, 0x74].
+ * const buf7 = Buffer.from('tést', 'latin1');
+ * ```
+ * @see [source](https://github.com/nodejs/node/blob/v16.4.2/lib/buffer.js)

+/**
+ * The `child_process` module provides the ability to spawn subprocesses in
+ * a manner that is similar, but not identical, to [`popen(3)`](http://man7.org/linux/man-pages/man3/popen.3.html). This capability
+ * is primarily provided by the {@link spawn} function:
+ *
+ * ```js
+ * const { spawn } = require('child_process');
+ * const ls = spawn('ls', ['-lh', '/usr']);
+ *
+ * ls.stdout.on('data', (data) => {
+ *   console.log(`stdout: ${data}`);
+ * });
+ *
+ * ls.stderr.on('data', (data) => {
+ *   console.error(`stderr: ${data}`);
+ * });
+ *
+ * ls.on('close', (code) => {
+ *   console.log(`child process exited with code ${code}`);
+ * });
+ * ```
+ *
+ * By default, pipes for `stdin`, `stdout`, and `stderr` are established between
+ * the parent Node.js process and the spawned subprocess. These pipes have
+ * limited (and platform-specific) capacity. If the subprocess writes to
+ * stdout in excess of that limit without the output being captured, the
+ * subprocess blocks waiting for the pipe buffer to accept more data. This is
+ * identical to the behavior of pipes in the shell. Use the `{ stdio: 'ignore' }`option if the output will not be consumed.
+ *
+ * The command lookup is performed using the `options.env.PATH` environment
+ * variable if it is in the `options` object. Otherwise, `process.env.PATH` is
+ * used.
+ *
+ * On Windows, environment variables are case-insensitive. Node.js
+ * lexicographically sorts the `env` keys and uses the first one that
+ * case-insensitively matches. Only first (in lexicographic order) entry will be
+ * passed to the subprocess. This might lead to issues on Windows when passing
+ * objects to the `env` option that have multiple variants of the same key, such as`PATH` and `Path`.
+ *
+ * The {@link spawn} method spawns the child process asynchronously,
+ * without blocking the Node.js event loop. The {@link spawnSync} function provides equivalent functionality in a synchronous manner that blocks
+ * the event loop until the spawned process either exits or is terminated.
+ *
+ * For convenience, the `child_process` module provides a handful of synchronous
+ * and asynchronous alternatives to {@link spawn} and {@link spawnSync}. Each of these alternatives are implemented on
+ * top of {@link spawn} or {@link spawnSync}.
+ *
+ * * {@link exec}: spawns a shell and runs a command within that
+ * shell, passing the `stdout` and `stderr` to a callback function when
+ * complete.
+ * * {@link execFile}: similar to {@link exec} except
+ * that it spawns the command directly without first spawning a shell by
+ * default.
+ * * {@link fork}: spawns a new Node.js process and invokes a
+ * specified module with an IPC communication channel established that allows
+ * sending messages between parent and child.
+ * * {@link execSync}: a synchronous version of {@link exec} that will block the Node.js event loop.
+ * * {@link execFileSync}: a synchronous version of {@link execFile} that will block the Node.js event loop.
+ *
+ * For certain use cases, such as automating shell scripts, the `synchronous counterparts` may be more convenient. In many cases, however,
+ * the synchronous methods can have significant impact on performance due to
+ * stalling the event loop while spawned processes complete.
+ * @see [source](https://github.com/nodejs/node/blob/v16.4.2/lib/child_process.js)

+         * When an IPC channel has been established between the parent and child (
+         * i.e. when using {@link fork}), the `subprocess.send()` method can
+         * be used to send messages to the child process. When the child process is a
+         * Node.js instance, these messages can be received via the `'message'` event.
+         *
+         * The message goes through serialization and parsing. The resulting
+         * message might not be the same as what is originally sent.
+         *
+         * For example, in the parent script:
+         *
+         * ```js
+         * const cp = require('child_process');
+         * const n = cp.fork(`${__dirname}/sub.js`);

+         *
+         * // Causes the child to print: CHILD got message: { hello: 'world' }
+         * n.send({ hello: 'world' });
+         * ```
+         *
+         * And then the child script, `'sub.js'` might look like this:
+         *
+         * ```js
+         * process.on('message', (m) => {
+         *   console.log('CHILD got message:', m);
+         * });
+         *
+         * // Causes the parent to print: PARENT got message: { foo: 'bar', baz: null }
+         * process.send({ foo: 'bar', baz: NaN });
+         * ```
+         *
+         * Child Node.js processes will have a `process.send()` method of their own
+         * that allows the child to send messages back to the parent.
+         *
+         * There is a special case when sending a `{cmd: 'NODE_foo'}` message. Messages
+         * containing a `NODE_` prefix in the `cmd` property are reserved for use within
+         * Node.js core and will not be emitted in the child's `'message'` event. Rather, such messages are emitted using the`'internalMessage'` event and are consumed internally by Node.js.
+         * Applications should avoid using such messages or listening for`'internalMessage'` events as it is subject to change without notice.
+         *
+         * The optional `sendHandle` argument that may be passed to `subprocess.send()` is
+         * for passing a TCP server or socket object to the child process. The child will
+         * receive the object as the second argument passed to the callback function
+         * registered on the `'message'` event. Any data that is received
+         * and buffered in the socket will not be sent to the child.
+         *
+         * The optional `callback` is a function that is invoked after the message is
+         * sent but before the child may have received it. The function is called with a
+         * single argument: `null` on success, or an `Error` object on failure.
+         *
+         * If no `callback` function is provided and the message cannot be sent, an`'error'` event will be emitted by the `ChildProcess` object. This can
+         * happen, for instance, when the child process has already exited.
+         *
+         * `subprocess.send()` will return `false` if the channel has closed or when the
+         * backlog of unsent messages exceeds a threshold that makes it unwise to send
+         * more. Otherwise, the method returns `true`. The `callback` function can be
+         * used to implement flow control.
+         *
+         * #### Example: sending a server object
+         *
+         * The `sendHandle` argument can be used, for instance, to pass the handle of
+         * a TCP server object to the child process as illustrated in the example below:
+         *
+         * ```js
+         * const subprocess = require('child_process').fork('subprocess.js');
+         *
+         * // Open up the server object and send the handle.
+         * const server = require('net').createServer();
+         * server.on('connection', (socket) => {
+         *   socket.end('handled by parent');
+         * });
+         * server.listen(1337, () => {
+         *   subprocess.send('server', server);
+         * });
+         * ```
+         *
+         * The child would then receive the server object as:
+         *
+         * ```js
+         * process.on('message', (m, server) => {
+         *   if (m === 'server') {
+         *     server.on('connection', (socket) => {
+         *       socket.end('handled by child');
+         *     });
+         *   }
+         * });
+         * ```
+         *
+         * Once the server is now shared between the parent and child, some connections
+         * can be handled by the parent and some by the child.
+         *
+         * While the example above uses a server created using the `net` module, `dgram`module servers use exactly the same workflow with the exceptions of listening on
+         * a `'message'` event instead of `'connection'` and using `server.bind()` instead
+         * of `server.listen()`. This is, however, currently only supported on Unix
+         * platforms.
+         *
+         * #### Example: sending a socket object
+         *
+         * Similarly, the `sendHandler` argument can be used to pass the handle of a
+         * socket to the child process. The example below spawns two children that each
+         * handle connections with "normal" or "special" priority:
+         *
+         * ```js
+         * const { fork } = require('child_process');
+         * const normal = fork('subprocess.js', ['normal']);
+         * const special = fork('subprocess.js', ['special']);
+         *
+         * // Open up the server and send sockets to child. Use pauseOnConnect to prevent
+         * // the sockets from being read before they are sent to the child process.
+         * const server = require('net').createServer({ pauseOnConnect: true });
+         * server.on('connection', (socket) => {
+         *
+         *   // If this is special priority...
+         *   if (socket.remoteAddress === '74.125.127.100') {
+         *     special.send('socket', socket);
+         *     return;
+         *   }
+         *   // This is normal priority.
+         *   normal.send('socket', socket);
+         * });
+         * server.listen(1337);
+         * ```
+         *
+         * The `subprocess.js` would receive the socket handle as the second argument
+         * passed to the event callback function:
+         *
+         * ```js
+         * process.on('message', (m, socket) => {
+         *   if (m === 'socket') {
+         *     if (socket) {
+         *       // Check that the client socket exists.
+         *       // It is possible for the socket to be closed between the time it is
+         *       // sent and the time it is received in the child process.
+         *       socket.end(`Request handled with ${process.argv[2]} priority`);
+         *     }
+         *   }
+         * });
+         * ```
+         *
+         * Do not use `.maxConnections` on a socket that has been passed to a subprocess.
+         * The parent cannot track when the socket is destroyed.
+         *
+         * Any `'message'` handlers in the subprocess should verify that `socket` exists,
+         * as the connection may have been closed during the time it takes to send the
+         * connection to the child.

+     * The `child_process.spawn()` method spawns a new process using the given`command`, with command-line arguments in `args`. If omitted, `args` defaults
+     * to an empty array.
+     *
+     * **If the `shell` option is enabled, do not pass unsanitized user input to this**
+     * **function. Any input containing shell metacharacters may be used to trigger**
+     * **arbitrary command execution.**
+     *
+     * A third argument may be used to specify additional options, with these defaults:
+     *
+     * ```js
+     * const defaults = {
+     *   cwd: undefined,
+     *   env: process.env
+     * };
+     * ```
+     *
+     * Use `cwd` to specify the working directory from which the process is spawned.
+     * If not given, the default is to inherit the current working directory. If given,
+     * but the path does not exist, the child process emits an `ENOENT` error
+     * and exits immediately. `ENOENT` is also emitted when the command
+     * does not exist.
+     *
+     * Use `env` to specify environment variables that will be visible to the new
+     * process, the default is `process.env`.
+     *
+     * `undefined` values in `env` will be ignored.
+     *
+     * Example of running `ls -lh /usr`, capturing `stdout`, `stderr`, and the
+     * exit code:
+     *
+     * ```js
+     * const { spawn } = require('child_process');
+     * const ls = spawn('ls', ['-lh', '/usr']);
+     *
+     * ls.stdout.on('data', (data) => {
+     *   console.log(`stdout: ${data}`);
+     * });
+     *
+     * ls.stderr.on('data', (data) => {
+     *   console.error(`stderr: ${data}`);
+     * });
+     *
+     * ls.on('close', (code) => {
+     *   console.log(`child process exited with code ${code}`);
+     * });
+     * ```
+     *
+     * Example: A very elaborate way to run `ps ax | grep ssh`
+     *
+     * ```js
+     * const { spawn } = require('child_process');
+     * const ps = spawn('ps', ['ax']);
+     * const grep = spawn('grep', ['ssh']);
+     *
+     * ps.stdout.on('data', (data) => {
+     *   grep.stdin.write(data);
+     * });
+     *
+     * ps.stderr.on('data', (data) => {
+     *   console.error(`ps stderr: ${data}`);
+     * });
+     *
+     * ps.on('close', (code) => {
+     *   if (code !== 0) {
+     *     console.log(`ps process exited with code ${code}`);
+     *   }
+     *   grep.stdin.end();
+     * });
+     *
+     * grep.stdout.on('data', (data) => {
+     *   console.log(data.toString());
+     * });
+     *
+     * grep.stderr.on('data', (data) => {
+     *   console.error(`grep stderr: ${data}`);
+     * });
+     *
+     * grep.on('close', (code) => {
+     *   if (code !== 0) {
+     *     console.log(`grep process exited with code ${code}`);
+     *   }
+     * });
+     * ```
+     *
+     * Example of checking for failed `spawn`:
+     *
+     * ```js
+     * const { spawn } = require('child_process');
+     * const subprocess = spawn('bad_command');
+     *
+     * subprocess.on('error', (err) => {
+     *   console.error('Failed to start subprocess.');
+     * });
+     * ```
+     *
+     * Certain platforms (macOS, Linux) will use the value of `argv[0]` for the process
+     * title while others (Windows, SunOS) will use `command`.
+     *
+     * Node.js currently overwrites `argv[0]` with `process.execPath` on startup, so`process.argv[0]` in a Node.js child process will not match the `argv0`parameter passed to `spawn` from the parent,
+     * retrieve it with the`process.argv0` property instead.
+     *
+     * If the `signal` option is enabled, calling `.abort()` on the corresponding`AbortController` is similar to calling `.kill()` on the child process except
+     * the error passed to the callback will be an `AbortError`:
+     *
+     * ```js
+     * const { spawn } = require('child_process');
+     * const controller = new AbortController();
+     * const { signal } = controller;
+     * const grep = spawn('grep', ['ssh'], { signal });
+     * grep.on('error', (err) => {
+     *   // This will be called with err being an AbortError if the controller aborts
+     * });
+     * controller.abort(); // Stops the child process
+     * ```
+     * @since v0.1.90
+     * @param command The command to run.
+     * @param args List of string arguments.

+     * `error.code` property will be
+     * the exit code of the process. By convention, any exit code other than `0`indicates an error. `error.signal` will be the signal that terminated the
+     * process.
+     *
+     * The `stdout` and `stderr` arguments passed to the callback will contain the
+     * stdout and stderr output of the child process. By default, Node.js will decode
+     * the output as UTF-8 and pass strings to the callback. The `encoding` option
+     * can be used to specify the character encoding used to decode the stdout and
+     * stderr output. If `encoding` is `'buffer'`, or an unrecognized character
+     * encoding, `Buffer` objects will be passed to the callback instead.
+     *
+     * ```js
+     * const { exec } = require('child_process');
+     * exec('cat *.js missing_file | wc -l', (error, stdout, stderr) => {
+     *   if (error) {
+     *     console.error(`exec error: ${error}`);
+     *     return;
+     *   }
+     *   console.log(`stdout: ${stdout}`);
+     *   console.error(`stderr: ${stderr}`);
+     * });
+     * ```
+     *
+     * If `timeout` is greater than `0`, the parent will send the signal
+     * identified by the `killSignal` property (the default is `'SIGTERM'`) if the
+     * child runs longer than `timeout` milliseconds.
+     *
+     * Unlike the [`exec(3)`](http://man7.org/linux/man-pages/man3/exec.3.html) POSIX system call, `child_process.exec()` does not replace
+     * the existing process and uses a shell to execute the command.
+     *
+     * If this method is invoked as its `util.promisify()` ed version, it returns
+     * a `Promise` for an `Object` with `stdout` and `stderr` properties. The returned`ChildProcess` instance is attached to the `Promise` as a `child` property. In
+     * case of an error (including any error resulting in an exit code other than 0), a
+     * rejected promise is returned, with the same `error` object given in the
+     * callback, but with two additional properties `stdout` and `stderr`.
+     *
+     * ```js
+     * const util = require('util');
+     * const exec = util.promisify(require('child_process').exec);
+     *
+     * async function lsExample() {
+     *   const { stdout, stderr } = await exec('ls');
+     *   console.log('stdout:', stdout);
+     *   console.error('stderr:', stderr);
+     * }
+     * lsExample();
+     * ```
+     *
+     * If the `signal` option is enabled, calling `.abort()` on the corresponding`AbortController` is similar to calling `.kill()` on the child process except
+     * the error passed to the callback will be an `AbortError`:
+     *
+     * ```js
+     * const { exec } = require('child_process');
+     * const controller = new AbortController();
+     * const { signal } = controller;
+     * const child = exec('grep ssh', { signal }, (error) => {
+     *   console.log(error); // an AbortError
+     * });
+     * controller.abort();
+     * ```
+     * @since v0.1.90
+     * @param command The command to run, with space-separated arguments.
+     * @param callback called with the output when process terminates.

+     * The `child_process.fork()` method is a special case of {@link spawn} used specifically to spawn new Node.js processes.
+     * Like {@link spawn}, a `ChildProcess` object is returned. The
+     * returned `ChildProcess` will have an additional communication channel
+     * built-in that allows messages to be passed back and forth between the parent and
+     * child. See `subprocess.send()` for details.
+     *
+     * Keep in mind that spawned Node.js child processes are
+     * independent of the parent with exception of the IPC communication channel
+     * that is established between the two. Each process has its own memory, with
+     * their own V8 instances. Because of the additional resource allocations
+     * required, spawning a large number of child Node.js processes is not
+     * recommended.
+     *
+     * By default, `child_process.fork()` will spawn new Node.js instances using the `process.execPath` of the parent process. The `execPath` property in the`options` object allows for an alternative
+     * execution path to be used.
+     *
+     * Node.js processes launched with a custom `execPath` will communicate with the
+     * parent process using the file descriptor (fd) identified using the
+     * environment variable `NODE_CHANNEL_FD` on the child process.
+     *
+     * Unlike the [`fork(2)`](http://man7.org/linux/man-pages/man2/fork.2.html) POSIX system call, `child_process.fork()` does not clone the
+     * current process.
+     *
+     * The `shell` option available in {@link spawn} is not supported by`child_process.fork()` and will be ignored if set.
+     *
+     * If the `signal` option is enabled, calling `.abort()` on the corresponding`AbortController` is similar to calling `.kill()` on the child process except
+     * the error passed to the callback will be an `AbortError`:
+     *
+     * ```js
+     * if (process.argv[2] === 'child') {
+     *   setTimeout(() => {
+     *     console.log(`Hello from ${process.argv[2]}!`);
+     *   }, 1_000);
+     * } else {
+     *   const { fork } = require('child_process');
+     *   const controller = new AbortController();
+     *   const { signal } = controller;
+     *   const child = fork(__filename, ['child'], { signal });
+     *   child.on('error', (err) => {
+     *     // This will be called with err being an AbortError if the controller aborts
+     *   });
+     *   controller.abort(); // Stops the child process
+     * }

+/**
+ * The `console` module provides a simple debugging console that is similar to the
+ * JavaScript console mechanism provided by web browsers.
+ *
+ * The module exports two specific components:
+ *
+ * * A `Console` class with methods such as `console.log()`, `console.error()` and`console.warn()` that can be used to write to any Node.js stream.
+ * * A global `console` instance configured to write to `process.stdout` and `process.stderr`. The global `console` can be used without calling`require('console')`.
+ *
+ * _**Warning**_: The global console object's methods are neither consistently
+ * synchronous like the browser APIs they resemble, nor are they consistently
+ * asynchronous like all other Node.js streams. See the `note on process I/O` for
+ * more information.
+ *
+ * Example using the global `console`:
+ *
+ * ```js
+ * console.log('hello world');
+ * // Prints: hello world, to stdout
+ * console.log('hello %s', 'world');
+ * // Prints: hello world, to stdout
+ * console.error(new Error('Whoops, something bad happened'));
+ * // Prints error message and stack trace to stderr:
+ * //   Error: Whoops, something bad happened
+ * //     at [eval]:5:15
+ * //     at Script.runInThisContext (node:vm:132:18)
+ * //     at Object.runInThisContext (node:vm:309:38)
+ * //     at node:internal/process/execution:77:19
+ * //     at [eval]-wrapper:6:22
+ * //     at evalScript (node:internal/process/execution:76:60)
+ * //     at node:internal/main/eval_string:23:3
+ *
+ * const name = 'Will Robinson';
+ * console.warn(`Danger ${name}! Danger!`);
+ * // Prints: Danger Will Robinson! Danger!, to stderr
+ * ```
+ *
+ * Example using the `Console` class:
+ *
+ * ```js
+ * const out = getStreamSomehow();
+ * const err = getStreamSomehow();
+ * const myConsole = new console.Console(out, err);
+ *
+ * myConsole.log('hello world');
+ * // Prints: hello world, to out
+ * myConsole.log('hello %s', 'world');
+ * // Prints: hello world, to out
+ * myConsole.error(new Error('Whoops, something bad happened'));
+ * // Prints: [Error: Whoops, something bad happened], to err
+ *
+ * const name = 'Will Robinson';
+ * myConsole.warn(`Danger ${name}! Danger!`);
+ * // Prints: Danger Will Robinson! Danger!, to err
+ * ```

+         * The `console` module provides a simple debugging console that is similar to the
+         * JavaScript console mechanism provided by web browsers.
+         *
+         * The module exports two specific components:
+         *
+         * * A `Console` class with methods such as `console.log()`, `console.error()` and`console.warn()` that can be used to write to any Node.js stream.
+         * * A global `console` instance configured to write to `process.stdout` and `process.stderr`. The global `console` can be used without calling`require('console')`.
+         *
+         * _**Warning**_: The global console object's methods are neither consistently
+         * synchronous like the browser APIs they resemble, nor are they consistently
+         * asynchronous like all other Node.js streams. See the `note on process I/O` for
+         * more information.
+         *
+         * Example using the global `console`:
+         *
+         * ```js
+         * console.log('hello world');
+         * // Prints: hello world, to stdout
+         * console.log('hello %s', 'world');
+         * // Prints: hello world, to stdout
+         * console.error(new Error('Whoops, something bad happened'));
+         * // Prints error message and stack trace to stderr:
+         * //   Error: Whoops, something bad happened
+         * //     at [eval]:5:15
+         * //     at Script.runInThisContext (node:vm:132:18)
+         * //     at Object.runInThisContext (node:vm:309:38)
+         * //     at node:internal/process/execution:77:19

+         * //     at node:internal/main/eval_string:23:3
+         *

+         * console.warn(`Danger ${name}! Danger!`);
+         * // Prints: Danger Will Robinson! Danger!, to stderr
+         * ```

+     *
+     * It is recommended to encode public keys as `'spki'` and private keys as`'pkcs8'` with encryption for long-term storage:

+     *     cipher: 'aes-256-cbc',
+     *     passphrase: 'top secret'
+     *   }
+     * }, (err, publicKey, privateKey) => {
+     *   // Handle errors and use the generated key pair.
+     * });
+     * ```
+     *
+     * ```js
+     * const {
+     *   generateKeyPair,
+     * } = require('crypto');
+     *
+     * generateKeyPair('rsa', {
+     *   modulusLength: 4096,
+     *   publicKeyEncoding: {
+     *     type: 'spki',
+     *     format: 'pem'
+     *   },
+     *   privateKeyEncoding: {

+     * }, (err, publicKey, privateKey) => {
+     *   // Handle errors and use the generated key pair.
+     * });
+     * ```
+     *
+     * On completion, `callback` will be called with `err` set to `undefined` and`publicKey` / `privateKey` representing the generated key pair.
+     *
+     * If this method is invoked as its `util.promisify()` ed version, it returns
+     * a `Promise` for an `Object` with `publicKey` and `privateKey` properties.
+     * @since v10.12.0
+     * @param type Must be `'rsa'`, `'dsa'`, `'ec'`, `'ed25519'`, `'ed448'`, `'x25519'`, `'x448'`, or `'dh'`.

+         *
+         * The `address` argument is a string. If the value of `address` is a host name,

+         * If the socket has not been previously bound with a call to `bind`, the socket

+         *
+         * An optional `callback` function may be specified to as a way of reporting

+         *
+         * Sets the default outgoing multicast interface of the socket to a chosen
+         * interface or back to system interface selection. The `multicastInterface` must
+         * be a valid string representation of an IP from the socket's family.
+         *
+         * For IPv4 sockets, this should be the IP configured for the desired physical
+         * interface. All packets sent to multicast on the socket will be sent on the
+         * interface determined by the most recent successful use of this call.
+         *
+         * For IPv6 sockets, `multicastInterface` should include a scope to indicate the
+         * interface as in the examples that follow. In IPv6, individual `send` calls can
+         * also use explicit scope in addresses, so only packets sent to a multicast
+         * address without specifying an explicit scope are affected by the most recent
+         * successful use of this call.
+         *
+         * This method throws `EBADF` if called on an unbound socket.
+         *
+         * #### Example: IPv6 outgoing multicast interface
+         *
+         * On most systems, where scope format uses the interface name:
+         *
+         * ```js
+         * const socket = dgram.createSocket('udp6');
+         *

+         *   socket.setMulticastInterface('::%eth1');
+         * });
+         * ```
+         *
+         * On Windows, where scope format uses an interface number:
+         *
+         * ```js
+         * const socket = dgram.createSocket('udp6');
+         *
+         * socket.bind(1234, () => {
+         *   socket.setMulticastInterface('::%2');
+         * });
+         * ```
+         *
+         * #### Example: IPv4 outgoing multicast interface
+         *
+         * All systems use an IP of the host on the desired physical interface:
+         *
+         * ```js
+         * const socket = dgram.createSocket('udp4');
+         *

+ * queries. These functions do not use the same set of configuration files used by {@link lookup} (e.g. `/etc/hosts`). Use these functions to always perform

+     * Resolves a host name (e.g. `'nodejs.org'`) into the first found A (IPv4) or
+     * AAAA (IPv6) record. All `option` properties are optional. If `options` is an
+     * integer, then it must be `4` or `6` – if `options` is not provided, then IPv4
+     * and IPv6 addresses are both returned if found.
+     *
+     * With the `all` option set to `true`, the arguments for `callback` change to`(err, addresses)`, with `addresses` being an array of objects with the
+     * properties `address` and `family`.
+     *
+     * On error, `err` is an `Error` object, where `err.code` is the error code.
+     * Keep in mind that `err.code` will be set to `'ENOTFOUND'` not only when
+     * the host name does not exist but also when the lookup fails in other ways
+     * such as no available file descriptors.
+     *
+     * `dns.lookup()` does not necessarily have anything to do with the DNS protocol.
+     * The implementation uses an operating system facility that can associate names
+     * with addresses, and vice versa. This implementation can have subtle but
+     * important consequences on the behavior of any Node.js program. Please take some
+     * time to consult the `Implementation considerations section` before using`dns.lookup()`.
+     *
+     * Example usage:
+     *
+     * ```js
+     * const dns = require('dns');
+     * const options = {
+     *   family: 6,
+     *   hints: dns.ADDRCONFIG | dns.V4MAPPED,
+     * };
+     * dns.lookup('example.com', options, (err, address, family) =>
+     *   console.log('address: %j family: IPv%s', address, family));
+     * // address: "2606:2800:220:1:248:1893:25c8:1946" family: IPv6
+     *
+     * // When options.all is true, the result will be an Array.
+     * options.all = true;
+     * dns.lookup('example.com', options, (err, addresses) =>
+     *   console.log('addresses: %j', addresses));
+     * // addresses: [{"address":"2606:2800:220:1:248:1893:25c8:1946","family":6}]
+     * ```
+     *
+     * If this method is invoked as its `util.promisify()` ed version, and `all`is not set to `true`, it returns a `Promise` for an `Object` with `address` and`family` properties.
+     * @since v0.1.90

+/**
+ * Much of the Node.js core API is built around an idiomatic asynchronous
+ * event-driven architecture in which certain kinds of objects (called "emitters")
+ * emit named events that cause `Function` objects ("listeners") to be called.
+ *
+ * For instance: a `net.Server` object emits an event each time a peer
+ * connects to it; a `fs.ReadStream` emits an event when the file is opened;
+ * a `stream` emits an event whenever data is available to be read.
+ *
+ * All objects that emit events are instances of the `EventEmitter` class. These
+ * objects expose an `eventEmitter.on()` function that allows one or more
+ * functions to be attached to named events emitted by the object. Typically,
+ * event names are camel-cased strings but any valid JavaScript property key
+ * can be used.
+ *
+ * When the `EventEmitter` object emits an event, all of the functions attached
+ * to that specific event are called _synchronously_. Any values returned by the
+ * called listeners are _ignored_ and discarded.
+ *
+ * The following example shows a simple `EventEmitter` instance with a single
+ * listener. The `eventEmitter.on()` method is used to register listeners, while
+ * the `eventEmitter.emit()` method is used to trigger the event.
+ *
+ * ```js
+ * const EventEmitter = require('events');
+ *
+ * class MyEmitter extends EventEmitter {}
+ *
+ * const myEmitter = new MyEmitter();
+ * myEmitter.on('event', () => {
+ *   console.log('an event occurred!');
+ * });
+ * myEmitter.emit('event');
+ * ```
+ * @see [source](https://github.com/nodejs/node/blob/v16.4.2/lib/events.js)

+     * When `file` is a filename, asynchronously writes data to the file, replacing the

+     * When `file` is a file descriptor, the behavior is similar to calling`fs.write()` directly (which is recommended). See the notes below on using
+     * a file descriptor.
+     *
+     * The `encoding` option is ignored if `data` is a buffer.
+     * If `data` is a normal object, it must have an own `toString` function property.
+     *
+     * ```js
+     * import { writeFile } from 'fs';
+     *
+     * const data = new Uint8Array(Buffer.from('Hello Node.js'));

+     *   console.log('The file has been saved!');
+     * });
+     * ```

+     * ```js
+     * import { writeFile } from 'fs';
+     *
+     * writeFile('message.txt', 'Hello Node.js', 'utf8', callback);
+     * ```
+     *
+     * It is unsafe to use `fs.writeFile()` multiple times on the same file without
+     * waiting for the callback. For this scenario, {@link createWriteStream} is
+     * recommended.
+     *
+     * Similarly to `fs.readFile` \- `fs.writeFile` is a convenience method that
+     * performs multiple `write` calls internally to write the buffer passed to it.
+     * For performance sensitive code consider using {@link createWriteStream}.
+     *
+     * It is possible to use an `<AbortSignal>` to cancel an `fs.writeFile()`.
+     * Cancelation is "best effort", and some amount of data is likely still
+     * to be written.
+     *
+     * ```js
+     * import { writeFile } from 'fs';
+     *
+     * const controller = new AbortController();
+     * const { signal } = controller;
+     * const data = new Uint8Array(Buffer.from('Hello Node.js'));

+     * });
+     * // When the request should be aborted
+     * controller.abort();
+     * ```
+     *
+     * Aborting an ongoing request does not abort individual operating

+/**
+ * To use the HTTP server and client one must `require('http')`.
+ *
+ * The HTTP interfaces in Node.js are designed to support many features
+ * of the protocol which have been traditionally difficult to use.
+ * In particular, large, possibly chunk-encoded, messages. The interface is
+ * careful to never buffer entire requests or responses, so the
+ * user is able to stream data.
+ *
+ * HTTP message headers are represented by an object like this:
+ *
+ * ```js
+ * { 'content-length': '123',
+ *   'content-type': 'text/plain',
+ *   'connection': 'keep-alive',
+ *   'host': 'mysite.com',
+ *   'accept': '*' }
+ * ```
+ *
+ * Keys are lowercased. Values are not modified.
+ *
+ * In order to support the full spectrum of possible HTTP applications, the Node.js
+ * HTTP API is very low-level. It deals with stream handling and message
+ * parsing only. It parses a message into headers and body but it does not
+ * parse the actual headers or the body.
+ *
+ * See `message.headers` for details on how duplicate headers are handled.
+ *
+ * The raw headers as they were received are retained in the `rawHeaders`property, which is an array of `[key, value, key2, value2, ...]`. For
+ * example, the previous message header object might have a `rawHeaders`list like the following:
+ *
+ * ```js
+ * [ 'ConTent-Length', '123456',
+ *   'content-LENGTH', '123',
+ *   'content-type', 'text/plain',
+ *   'CONNECTION', 'keep-alive',
+ *   'Host', 'mysite.com',
+ *   'accepT', '*' ]
+ * ```
+ * @see [source](https://github.com/nodejs/node/blob/v16.4.2/lib/http.js)

+     * * Sending a 'Connection: keep-alive' will notify Node.js that the connection to
+     * the server should be persisted until the next request.
+     * * Sending a 'Content-Length' header will disable the default chunked encoding.
+     * * Sending an 'Expect' header will immediately send the request headers.
+     * Usually, when sending 'Expect: 100-continue', both a timeout and a listener
+     * for the `'continue'` event should be set. See RFC 2616 Section 8.2.3 for more
+     * information.
+     * * Sending an Authorization header will override using the `auth` option
+     * to compute basic authentication.
+     *
+     * Example using a `URL` as `options`:
+     *
+     * ```js
+     * const options = new URL('http://abc:xyz@example.com');
+     *
+     * const req = http.request(options, (res) => {
+     *   // ...
+     * });
+     * ```
+     *
+     * In a successful request, the following events will be emitted in the following
+     * order:
+     *
+     * * `'socket'`

+                 * set. Node.js will not terminate until all the `'exit'` event listeners are
+                 * called.
+                 *
+                 * To exit with a 'failure' code:

+                 * ```js

+                 *
+                 * The shell that executed Node.js should see the exit code as `1`.
+                 *
+                 * Calling `process.exit()` will force the process to exit as quickly as possible
+                 * even if there are still asynchronous operations pending that have not yet
+                 * completed fully, including I/O operations to `process.stdout` and`process.stderr`.
+                 *
+                 * In most situations, it is not actually necessary to call `process.exit()`explicitly. The Node.js process will exit on its own _if there is no additional_
+                 * _work pending_ in the event loop. The `process.exitCode` property can be set to
+                 * tell the process which exit code to use when the process exits gracefully.
+                 *
+                 * For instance, the following example illustrates a _misuse_ of the`process.exit()` method that could lead to data printed to stdout being
+                 * truncated and lost:
+                 *
+                 * ```js
+                 * // This is an example of what *not* to do:
+                 * if (someConditionNotMet()) {
+                 *   printUsageToStdout();
+                 *   process.exit(1);
+                 * }
+                 * ```
+                 *
+                 * The reason this is problematic is because writes to `process.stdout` in Node.js
+                 * are sometimes _asynchronous_ and may occur over multiple ticks of the Node.js
+                 * event loop. Calling `process.exit()`, however, forces the process to exit_before_ those additional writes to `stdout` can be performed.
+                 *
+                 * Rather than calling `process.exit()` directly, the code _should_ set the`process.exitCode` and allow the process to exit naturally by avoiding
+                 * scheduling any additional work for the event loop:
+                 *
+                 * ```js
+                 * // How to properly set the exit code while letting
+                 * // the process exit gracefully.

+ *
+ * ```js

+ *
+ * [Punycode](https://tools.ietf.org/html/rfc3492) is a character encoding scheme defined by RFC 3492 that is
+ * primarily intended for use in Internationalized Domain Names. Because host
+ * names in URLs are limited to ASCII characters only, Domain Names that contain
+ * non-ASCII characters must be converted into ASCII using the Punycode scheme.
+ * For instance, the Japanese character that translates into the English word,`'example'` is `'例'`. The Internationalized Domain Name, `'例.com'` (equivalent
+ * to `'example.com'`) is represented by Punycode as the ASCII string`'xn--fsq.com'`.
+ *
+ * The `punycode` module provides a simple implementation of the Punycode standard.
+ *
+ * The `punycode` module is a third-party dependency used by Node.js and
+ * made available to developers as a convenience. Fixes or other modifications to
+ * the module must be directed to the [Punycode.js](https://github.com/bestiejs/punycode.js) project.

+     *
+     * ## Example: Tiny CLI
+     *
+     * The following example illustrates the use of `readline.Interface` class to
+     * implement a small command-line interface:
+     *
+     * ```js
+     * const readline = require('readline');
+     * const rl = readline.createInterface({
+     *   input: process.stdin,
+     *   output: process.stdout,
+     *   prompt: 'OHAI> '
+     * });
+     *
+     * rl.prompt();
+     *
+     * rl.on('line', (line) => {
+     *   switch (line.trim()) {
+     *     case 'hello':
+     *       console.log('world!');
+     *       break;
+     *     default:
+     *       console.log(`Say what? I might have heard '${line.trim()}'`);
+     *       break;
+     *   }
+     *   rl.prompt();
+     * }).on('close', () => {
+     *   console.log('Have a great day!');
+     *   process.exit(0);
+     * });
+     * ```
+     *
+     * ## Example: Read file stream line-by-Line
+     *
+     * A common use case for `readline` is to consume an input file one line at a
+     * time. The easiest way to do so is leveraging the `fs.ReadStream` API as
+     * well as a `for await...of` loop:
+     *
+     * ```js
+     * const fs = require('fs');
+     * const readline = require('readline');
+     *
+     * async function processLineByLine() {
+     *   const fileStream = fs.createReadStream('input.txt');
+     *
+     *   const rl = readline.createInterface({
+     *     input: fileStream,
+     *     crlfDelay: Infinity
+     *   });
+     *   // Note: we use the crlfDelay option to recognize all instances of CR LF
+     *   // ('\r\n') in input.txt as a single line break.
+     *
+     *   for await (const line of rl) {
+     *     // Each line in input.txt will be successively available here as `line`.
+     *     console.log(`Line from file: ${line}`);
+     *   }
+     * }
+     *
+     * processLineByLine();
+     * ```
+     *
+     * Alternatively, one could use the `'line'` event:
+     *
+     * ```js
+     * const fs = require('fs');
+     * const readline = require('readline');
+     *
+     * const rl = readline.createInterface({
+     *   input: fs.createReadStream('sample.txt'),
+     *   crlfDelay: Infinity
+     * });
+     *
+     * rl.on('line', (line) => {
+     *   console.log(`Line from file: ${line}`);
+     * });
+     * ```
+     *
+     * Currently, `for await...of` loop can be a bit slower. If `async` / `await`flow and speed are both essential, a mixed approach can be applied:
+     *
+     * ```js
+     * const { once } = require('events');
+     * const { createReadStream } = require('fs');
+     * const { createInterface } = require('readline');
+     *
+     * (async function processLineByLine() {
+     *   try {
+     *     const rl = createInterface({
+     *       input: createReadStream('big-file.txt'),
+     *       crlfDelay: Infinity
+     *     });
+     *
+     *     rl.on('line', (line) => {
+     *       // Process the line.
+     *     });
+     *
+     *     await once(rl, 'close');
+     *
+     *     console.log('File processed.');
+     *   } catch (err) {
+     *     console.error(err);
+     *   }
+     * })();
+     * ```
+     * @since v0.7.7
+     * @param callback Invoked once the operation completes.
+     * @return `false` if `stream` wishes for the calling code to wait for the `'drain'` event to be emitted before continuing to write additional data; otherwise `true`.

+         * prematurely (like an aborted HTTP request), and will not emit `'end'`or `'finish'`.
+         *
+         * The `finished` API provides promise version:
+         *

+         * const { finished } = require('stream/promises');
+         *

+         * rs.resume(); // Drain the stream.
+         * ```
+         *
+         * `stream.finished()` leaves dangling event listeners (in particular`'error'`, `'end'`, `'finish'` and `'close'`) after `callback` has been
+         * invoked. The reason for this is so that unexpected `'error'` events (due to
+         * incorrect stream implementations) do not cause unexpected crashes.
+         * If this is unwanted behavior then the returned cleanup function needs to be
+         * invoked in the callback:
+         *
+         * ```js
+         * const cleanup = finished(rs, (err) => {
+         *   cleanup();
+         *   // ...
+         * });
+         * ```
+         * @since v10.0.0
+         * @param stream A readable and/or writable stream.
+         * @param callback A callback function that takes an optional error argument.

+ * ```js
+ * const { StringDecoder } = require('string_decoder');

+ *
+ * The following example shows the basic use of the `StringDecoder` class.
+ *

+ * const decoder = new StringDecoder('utf8');
+ *
+ * const cent = Buffer.from([0xC2, 0xA2]);

+ *
+ * const euro = Buffer.from([0xE2, 0x82, 0xAC]);
+ * console.log(decoder.write(euro));
+ * ```
+ *

+ * The `trace_events` module provides a mechanism to centralize tracing information
+ * generated by V8, Node.js core, and userspace code.
+ *
+ * Tracing can be enabled with the `--trace-event-categories` command-line flag
+ * or by using the `trace_events` module. The `--trace-event-categories` flag
+ * accepts a list of comma-separated category names.
+ *
+ * The available categories are:
+ *
+ * * `node`: An empty placeholder.
+ * * `node.async_hooks`: Enables capture of detailed `async_hooks` trace data.
+ * The `async_hooks` events have a unique `asyncId` and a special `triggerId` `triggerAsyncId` property.
+ * * `node.bootstrap`: Enables capture of Node.js bootstrap milestones.
+ * * `node.console`: Enables capture of `console.time()` and `console.count()`output.
+ * * `node.dns.native`: Enables capture of trace data for DNS queries.
+ * * `node.environment`: Enables capture of Node.js Environment milestones.
+ * * `node.fs.sync`: Enables capture of trace data for file system sync methods.
+ * * `node.perf`: Enables capture of `Performance API` measurements.
+ *    * `node.perf.usertiming`: Enables capture of only Performance API User Timing
+ *    measures and marks.
+ *    * `node.perf.timerify`: Enables capture of only Performance API timerify
+ *    measurements.
+ * * `node.promises.rejections`: Enables capture of trace data tracking the number
+ * of unhandled Promise rejections and handled-after-rejections.
+ * * `node.vm.script`: Enables capture of trace data for the `vm` module's`runInNewContext()`, `runInContext()`, and `runInThisContext()` methods.
+ * * `v8`: The `V8` events are GC, compiling, and execution related.
+ *
+ * By default the `node`, `node.async_hooks`, and `v8` categories are enabled.
+ *
+ * ```bash
+ * node --trace-event-categories v8,node,node.async_hooks server.js
+ * ```
+ *
+ * Prior versions of Node.js required the use of the `--trace-events-enabled`flag to enable trace events. This requirement has been removed. However, the`--trace-events-enabled` flag _may_ still be
+ * used and will enable the`node`, `node.async_hooks`, and `v8` trace event categories by default.
+ *
+ * ```bash
+ * node --trace-events-enabled
+ *
+ * # is equivalent to
+ *
+ * node --trace-event-categories v8,node,node.async_hooks
+ * ```
+ *
+ * Alternatively, trace events may be enabled using the `trace_events` module:
+ *
+ * ```js
+ * const trace_events = require('trace_events');
+ * const tracing = trace_events.createTracing({ categories: ['node.perf'] });
+ * tracing.enable();  // Enable trace event capture for the 'node.perf' category
+ *
+ * // do work
+ *
+ * tracing.disable();  // Disable trace event capture for the 'node.perf' category
+ * ```
+ *
+ * Running Node.js with tracing enabled will produce log files that can be opened
+ * in the [`chrome://tracing`](https://www.chromium.org/developers/how-tos/trace-event-profiling-tool)tab of Chrome.
+ *
+ * The logging file is by default called `node_trace.${rotation}.log`, where`${rotation}` is an incrementing log-rotation id. The filepath pattern can
+ * be specified with `--trace-event-file-pattern` that accepts a template
+ * string that supports `${rotation}` and `${pid}`:
+ *
+ * ```bash
+ * node --trace-event-categories v8 --trace-event-file-pattern '${pid}-${rotation}.log' server.js
+ * ```
+ *
+ * The tracing system uses the same time source
+ * as the one used by `process.hrtime()`.
+ * However the trace-event timestamps are expressed in microseconds,
+ * unlike `process.hrtime()` which returns nanoseconds.
+ *
+ * The features from this module are not available in `Worker` threads.

+/**
+ * The `vm` module enables compiling and running code within V8 Virtual
+ * Machine contexts. **The `vm` module is not a security mechanism. Do**
+ * **not use it to run untrusted code**.
+ *
+ * JavaScript code can be compiled and run immediately or
+ * compiled, saved, and run later.
+ *
+ * A common use case is to run the code in a different V8 Context. This means
+ * invoked code has a different global object than the invoking code.
+ *
+ * One can provide the context by `contextifying` an
+ * object. The invoked code treats any property in the context like a
+ * global variable. Any changes to global variables caused by the invoked
+ * code are reflected in the context object.
+ *
+ * ```js
+ * const vm = require('vm');
+ *
+ * const x = 1;
+ *
+ * const context = { x: 2 };
+ * vm.createContext(context); // Contextify the object.
+ *
+ * const code = 'x += 40; var y = 17;';
+ * // `x` and `y` are global variables in the context.
+ * // Initially, x has the value 2 because that is the value of context.x.
+ * vm.runInContext(code, context);
+ *
+ * console.log(context.x); // 42
+ * console.log(context.y); // 17
+ *
+ * console.log(x); // 1; y is not defined.

+     * Because `vm.runInThisContext()` does not have access to the local scope,`localVar` is unchanged. In contrast,
+     * [`eval()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/eval)_does_ have access to the
+     * local scope, so the value `localVar` is changed. In this way`vm.runInThisContext()` is much like an [indirect `eval()` call](https://es5.github.io/#x10.4.2), e.g.`(0,eval)('code')`.
+     *
+     * ## Example: Running an HTTP server within a VM
+     *
+     * When using either `script.runInThisContext()` or {@link runInThisContext}, the code is executed within the current V8 global
+     * context. The code passed to this VM context will have its own isolated scope.
+     *
+     * In order to run a simple web server using the `http` module the code passed to
+     * the context must either call `require('http')` on its own, or have a reference
+     * to the `http` module passed to it. For instance:
+     *
+     * ```js
+     * 'use strict';
+     * const vm = require('vm');
+     *
+     * const code = `
+     * ((require) => {
+     *   const http = require('http');
+     *
+     *   http.createServer((request, response) => {
+     *     response.writeHead(200, { 'Content-Type': 'text/plain' });
+     *     response.end('Hello World\\n');
+     *   }).listen(8124);
+     *
+     *   console.log('Server running at http://127.0.0.1:8124/');
+     * })`;
+     *
+     * vm.runInThisContext(code)(require);
+     * ```
+     *
+     * The `require()` in the above case shares the state with the context it is
+     * passed from. This may introduce risks when untrusted code is executed, e.g.
+     * altering objects in the context in unwanted ways.

+/**
+ * The `worker_threads` module enables the use of threads that execute JavaScript
+ * in parallel. To access it:
+ *
+ * ```js
+ * const worker = require('worker_threads');
+ * ```
+ *
+ * Workers (threads) are useful for performing CPU-intensive JavaScript operations.
+ * They do not help much with I/O-intensive work. The Node.js built-in
+ * asynchronous I/O operations are more efficient than Workers can be.
+ *
+ * Unlike `child_process` or `cluster`, `worker_threads` can share memory. They do
+ * so by transferring `ArrayBuffer` instances or sharing `SharedArrayBuffer`instances.
+ *
+ * ```js
+ * const {
+ *   Worker, isMainThread, parentPort, workerData
+ * } = require('worker_threads');
+ *
+ * if (isMainThread) {
+ *   module.exports = function parseJSAsync(script) {
+ *     return new Promise((resolve, reject) => {
+ *       const worker = new Worker(__filename, {
+ *         workerData: script
+ *       });
+ *       worker.on('message', resolve);
+ *       worker.on('error', reject);
+ *       worker.on('exit', (code) => {
+ *         if (code !== 0)
+ *           reject(new Error(`Worker stopped with exit code ${code}`));
+ *       });
+ *     });
+ *   };
+ * } else {
+ *   const { parse } = require('some-js-parsing-library');
+ *   const script = workerData;
+ *   parentPort.postMessage(parse(script));
+ * }
+ * ```
+ *
+ * The above example spawns a Worker thread for each `parse()` call. In actual
+ * practice, use a pool of Workers for these kinds of tasks. Otherwise, the
+ * overhead of creating Workers would likely exceed their benefit.
+ *
+ * When implementing a worker pool, use the `AsyncResource` API to inform
+ * diagnostic tools (e.g. to provide asynchronous stack traces) about the
+ * correlation between tasks and their outcomes. See `"Using AsyncResource for a Worker thread pool"` in the `async_hooks` documentation for an example implementation.
+ *
+ * Worker threads inherit non-process-specific options by default. Refer to `Worker constructor options` to know how to customize worker thread options,
+ * specifically `argv` and `execArgv` options.
+ * @see [source](https://github.com/nodejs/node/blob/v16.4.2/lib/worker_threads.js)

+     *
+     * * The `process.stdin`, `process.stdout` and `process.stderr` may be redirected by the parent thread.
+     * * The `require('worker_threads').isMainThread` property is set to `false`.
+     * * The `require('worker_threads').parentPort` message port is available.
+     * * `process.exit()` does not stop the whole program, just the single thread,
+     * and `process.abort()` is not available.
+     * * `process.chdir()` and `process` methods that set group or user ids
+     * are not available.
+     * * `process.env` is a copy of the parent thread's environment variables,
+     * unless otherwise specified. Changes to one copy are not visible in other
+     * threads, and are not visible to native add-ons (unless `worker.SHARE_ENV` is passed as the `env` option to the `Worker` constructor).
+     * * `process.title` cannot be modified.
+     * * Signals are not delivered through `process.on('...')`.
+     * * Execution may stop at any point as a result of `worker.terminate()` being invoked.
+     * * IPC channels from parent processes are not accessible.
+     * * The `trace_events` module is not supported.
+     * * Native add-ons can only be loaded from multiple threads if they fulfill `certain conditions`.
+     *
+     * Creating `Worker` instances inside of other `Worker`s is possible.
+     *
+     * Like [Web Workers](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API) and the `cluster module`, two-way communication can be
+     * achieved through inter-thread message passing. Internally, a `Worker` has a
+     * built-in pair of `MessagePort` s that are already associated with each other
+     * when the `Worker` is created. While the `MessagePort` object on the parent side
+     * is not directly exposed, its functionalities are exposed through `worker.postMessage()` and the `worker.on('message')` event
+     * on the `Worker` object for the parent thread.
+     *
+     * To create custom messaging channels (which is encouraged over using the default
+     * global channel because it facilitates separation of concerns), users can create
+     * a `MessageChannel` object on either thread and pass one of the`MessagePort`s on that `MessageChannel` to the other thread through a
+     * pre-existing channel, such as the global one.
+     *
+     * See `port.postMessage()` for more information on how messages are passed,
+     * and what kind of JavaScript values can be successfully transported through
+     * the thread barrier.
+     *
+     * ```js
+     * const assert = require('assert');

+/**
+ * The `zlib` module provides compression functionality implemented using Gzip,
+ * Deflate/Inflate, and Brotli.
+ *
+ * To access it:
+ *
+ * ```js
+ * const zlib = require('zlib');
+ * ```
+ *
+ * Compression and decompression are built around the Node.js `Streams API`.
+ *
+ * Compressing or decompressing a stream (such as a file) can be accomplished by
+ * piping the source stream through a `zlib` `Transform` stream into a destination
+ * stream:
+ *
+ * ```js
+ * const { createGzip } = require('zlib');
+ * const { pipeline } = require('stream');
+ * const {
+ *   createReadStream,
+ *   createWriteStream
+ * } = require('fs');
+ *
+ * const gzip = createGzip();
+ * const source = createReadStream('input.txt');
+ * const destination = createWriteStream('input.txt.gz');
+ *
+ * pipeline(source, gzip, destination, (err) => {
+ *   if (err) {
+ *     console.error('An error occurred:', err);
+ *     process.exitCode = 1;
+ *   }
+ * });
+ *
+ * // Or, Promisified
+ *
+ * const { promisify } = require('util');
+ * const pipe = promisify(pipeline);
+ *
+ * async function do_gzip(input, output) {
+ *   const gzip = createGzip();
+ *   const source = createReadStream(input);
+ *   const destination = createWriteStream(output);
+ *   await pipe(source, gzip, destination);
+ * }
+ *
+ * do_gzip('input.txt', 'input.txt.gz')
+ *   .catch((err) => {
+ *     console.error('An error occurred:', err);
+ *     process.exitCode = 1;
+ *   });
+ * ```
+ *
+ * It is also possible to compress or decompress data in a single step:
+ *
+ * ```js
+ * const { deflate, unzip } = require('zlib');
+ *
+ * const input = '.................................';
+ * deflate(input, (err, buffer) => {
+ *   if (err) {
+ *     console.error('An error occurred:', err);
+ *     process.exitCode = 1;
+ *   }
+ *   console.log(buffer.toString('base64'));
+ * });
+ *
+ * const buffer = Buffer.from('eJzT0yMAAGTvBe8=', 'base64');
+ * unzip(buffer, (err, buffer) => {
+ *   if (err) {
+ *     console.error('An error occurred:', err);
+ *     process.exitCode = 1;
+ *   }
+ *   console.log(buffer.toString());
+ * });
+ *
+ * // Or, Promisified
+ *
+ * const { promisify } = require('util');
+ * const do_unzip = promisify(unzip);
+ *
+ * do_unzip(buffer)
+ *   .then((buf) => console.log(buf.toString()))
+ *   .catch((err) => {
+ *     console.error('An error occurred:', err);

+
+JavaScript implementation of the timer APIs; `setTimeout`, `clearTimeout`, `setImmediate`, `clearImmediate`, `setInterval`, `clearInterval`, `requestAnimationFrame`, `cancelAnimationFrame`, `requestIdleCallback`, and `cancelIdleCallback`, along with a clock instance that controls the flow of time. FakeTimers also provides a `Date` implementation that gets its time from the clock.
+
+In addition in browser environment `@sinonjs/fake-timers` provides a `performance` implementation that gets its time from the clock. In Node environments FakeTimers provides a `nextTick` implementation that is synchronized with the clock - and a `process.hrtime` shim that works with the clock.
+
+`@sinonjs/fake-timers` can be used to simulate passing time in automated tests and other
+situations where you want the scheduling semantics, but don't want to actually
+wait.
+
+`@sinonjs/fake-timers` is extracted from [Sinon.JS](https://github.com/sinonjs/sinon.js) and targets the [same runtimes](https://sinonjs.org/releases/latest/#supported-runtimes).
+
+## Help us get our TypeScript definitions production ready!
+
+In version 7 we introduced TypeScript definitions that are generated from our JSDoc. This makes importing types from [DefinitelyTyped](https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/sinonjs__fake-timers/index.d.ts) superfluous, but we have just gotten started and we need your work for this to be up to the same quality. Until that happens typings from DefinitelyTyped still can be used:
+
+```sh
+npm install -D @types/sinonjs__fake-timers
+```
+
+Add this to tsconfig.json
+
+```
+{
+  "compilerOptions": {
+    ...
+    "paths": {
+      ...
+      "@sinonjs/fake-timers": ["node_modules/@types/sinonjs__fake-timers"]
+    }
+  }
+}
+```
+
+## Installation
+
+`@sinonjs/fake-timers` can be used in both Node and browser environments. Installation is as easy as
+
+```sh
+npm install @sinonjs/fake-timers
+```
+
+If you want to use `@sinonjs/fake-timers` in a browser you can either build your own bundle or use [Skypack](https://www.skypack.dev).
+
+## Usage
+
+To use `@sinonjs/fake-timers`, create a new clock, schedule events on it using the timer
+functions and pass time using the `tick` method.
+
+```js
+// In the browser distribution, a global `FakeTimers` is already available
+var FakeTimers = require("@sinonjs/fake-timers");
+var clock = FakeTimers.createClock();
+
+clock.setTimeout(function () {
+    console.log(
+        "The poblano is a mild chili pepper originating in the state of Puebla, Mexico."
+    );
+}, 15);
+
+// ...
+
+clock.tick(15);
+```
+
+Upon executing the last line, an interesting fact about the
+[Poblano](https://en.wikipedia.org/wiki/Poblano) will be printed synchronously to
+the screen. If you want to simulate asynchronous behavior, you have to use your
+imagination when calling the various functions.
+
+The `next`, `runAll`, `runToFrame`, and `runToLast` methods are available to advance the clock. See the
+API Reference for more details.
+
+### Faking the native timers
+
+When using `@sinonjs/fake-timers` to test timers, you will most likely want to replace the native
+timers such that calling `setTimeout` actually schedules a callback with your
+clock instance, not the browser's internals.
+
+Calling `install` with no arguments achieves this. You can call `uninstall`
+later to restore things as they were again.
+
+```js
+// In the browser distribution, a global `FakeTimers` is already available
+var FakeTimers = require("@sinonjs/fake-timers");
+
+var clock = FakeTimers.install();
+// Equivalent to
+// var clock = FakeTimers.install(typeof global !== "undefined" ? global : window);
+
+setTimeout(fn, 15); // Schedules with clock.setTimeout
+
+clock.uninstall();
+// setTimeout is restored to the native implementation
+```
+
+To hijack timers in another context pass it to the `install` method.
+
+```js
+var FakeTimers = require("@sinonjs/fake-timers");
+var context = {
+    setTimeout: setTimeout, // By default context.setTimeout uses the global setTimeout
+};
+var clock = FakeTimers.withGlobal(context).install();
+
+context.setTimeout(fn, 15); // Schedules with clock.setTimeout
+
+clock.uninstall();
+// context.setTimeout is restored to the original implementation
+```
+
+Usually you want to install the timers onto the global object, so call `install`
+without arguments.
+
+#### Automatically incrementing mocked time
+
+FakeTimers supports the possibility to attach the faked timers to any change
+in the real system time. This means that there is no need to `tick()` the
+clock in a situation where you won't know **when** to call `tick()`.
+
+Please note that this is achieved using the original setImmediate() API at a certain
+configurable interval `config.advanceTimeDelta` (default: 20ms). Meaning time would
+be incremented every 20ms, not in real time.
+
+An example would be:
+
+```js
+var FakeTimers = require("@sinonjs/fake-timers");
+var clock = FakeTimers.install({
+    shouldAdvanceTime: true,
+    advanceTimeDelta: 40,
+});
+
+setTimeout(() => {
+    console.log("this just timed out"); //executed after 40ms
+}, 30);
+
+setImmediate(() => {
+    console.log("not so immediate"); //executed after 40ms
+});
+
+setTimeout(() => {
+    console.log("this timed out after"); //executed after 80ms
+    clock.uninstall();
+}, 50);
+```
+
+## API Reference
+
+### `var clock = FakeTimers.createClock([now[, loopLimit]])`
+
+Creates a clock. The default
+[epoch](https://en.wikipedia.org/wiki/Epoch_%28reference_date%29) is `0`.
+
+The `now` argument may be a number (in milliseconds) or a Date object.
+
+The `loopLimit` argument sets the maximum number of timers that will be run when calling `runAll()` before assuming that we have an infinite loop and throwing an error. The default is `1000`.
+
+### `var clock = FakeTimers.install([config])`
+
+Installs FakeTimers using the specified config (otherwise with epoch `0` on the global scope). The following configuration options are available
+

+
+### `var id = clock.setTimeout(callback, timeout)`
+
+Schedules the callback to be fired once `timeout` milliseconds have ticked by.
+
+In Node.js `setTimeout` returns a timer object. FakeTimers will do the same, however
+its `ref()` and `unref()` methods have no effect.
+
+In browsers a timer ID is returned.
+
+### `clock.clearTimeout(id)`
+
+Clears the timer given the ID or timer object, as long as it was created using
+`setTimeout`.
+
+### `var id = clock.setInterval(callback, timeout)`
+
+Schedules the callback to be fired every time `timeout` milliseconds have ticked
+by.
+
+In Node.js `setInterval` returns a timer object. FakeTimers will do the same, however
+its `ref()` and `unref()` methods have no effect.
+
+In browsers a timer ID is returned.
+
+### `clock.clearInterval(id)`
+
+Clears the timer given the ID or timer object, as long as it was created using
+`setInterval`.
+
+### `var id = clock.setImmediate(callback)`
+
+Schedules the callback to be fired once `0` milliseconds have ticked by. Note
+that you'll still have to call `clock.tick()` for the callback to fire. If
+called during a tick the callback won't fire until `1` millisecond has ticked
+by.
+
+In Node.js `setImmediate` returns a timer object. FakeTimers will do the same,
+however its `ref()` and `unref()` methods have no effect.
+
+In browsers a timer ID is returned.
+
+### `clock.clearImmediate(id)`
+
+Clears the timer given the ID or timer object, as long as it was created using
+`setImmediate`.
+
+### `clock.requestAnimationFrame(callback)`
+
+Schedules the callback to be fired on the next animation frame, which runs every
+16 ticks. Returns an `id` which can be used to cancel the callback. This is
+available in both browser & node environments.
+
+### `clock.cancelAnimationFrame(id)`
+
+Cancels the callback scheduled by the provided id.
+
+### `clock.requestIdleCallback(callback[, timeout])`
+
+Queued the callback to be fired during idle periods to perform background and low priority work on the main event loop. Callbacks which have a timeout option will be fired no later than time in milliseconds. Returns an `id` which can be used to cancel the callback.
+
+### `clock.cancelIdleCallback(id)`
+
+Cancels the callback scheduled by the provided id.
+
+### `clock.countTimers()`
+
+Returns the number of waiting timers. This can be used to assert that a test
+finishes without leaking any timers.
+
+### `clock.hrtime(prevTime?)`
+
+Only available in Node.js, mimicks process.hrtime().
+
+### `clock.nextTick(callback)`
+
+Only available in Node.js, mimics `process.nextTick` to enable completely synchronous testing flows.
+
+### `clock.performance.now()`
+
+Only available in browser environments, mimicks performance.now().
+
+### `clock.tick(time)` / `await clock.tickAsync(time)`
+
+Advance the clock, firing callbacks if necessary. `time` may be the number of
+milliseconds to advance the clock by or a human-readable string. Valid string
+formats are `"08"` for eight seconds, `"01:00"` for one minute and `"02:34:10"`
+for two hours, 34 minutes and ten seconds.
+
+The `tickAsync()` will also break the event loop, allowing any scheduled promise
+callbacks to execute _before_ running the timers.
+
+### `clock.next()` / `await clock.nextAsync()`
+
+Advances the clock to the the moment of the first scheduled timer, firing it.
+
+The `nextAsync()` will also break the event loop, allowing any scheduled promise
+callbacks to execute _before_ running the timers.
+
+### `clock.reset()`
+
+Removes all timers and ticks without firing them, and sets `now` to `config.now`
+that was provided to `FakeTimers.install` or to `0` if `config.now` was not provided.
+Useful to reset the state of the clock without having to `uninstall` and `install` it.
+
+### `clock.runAll()` / `await clock.runAllAsync()`
+
+This runs all pending timers until there are none remaining. If new timers are added while it is executing they will be run as well.
+
+This makes it easier to run asynchronous tests to completion without worrying about the number of timers they use, or the delays in those timers.
+
+It runs a maximum of `loopLimit` times after which it assumes there is an infinite loop of timers and throws an error.
+
+The `runAllAsync()` will also break the event loop, allowing any scheduled promise
+callbacks to execute _before_ running the timers.
+
+### `clock.runMicrotasks()`
+
+This runs all pending microtasks scheduled with `nextTick` but none of the timers and is mostly useful for libraries using FakeTimers underneath and for running `nextTick` items without any timers.
+
+### `clock.runToFrame()`
+
+Advances the clock to the next frame, firing all scheduled animation frame callbacks,
+if any, for that frame as well as any other timers scheduled along the way.
+
+### `clock.runToLast()` / `await clock.runToLastAsync()`
+
+This takes note of the last scheduled timer when it is run, and advances the
+clock to that time firing callbacks as necessary.
+
+If new timers are added while it is executing they will be run only if they
+would occur before this time.
+
+This is useful when you want to run a test to completion, but the test recursively
+sets timers that would cause `runAll` to trigger an infinite loop warning.
+
+The `runToLastAsync()` will also break the event loop, allowing any scheduled promise
+callbacks to execute _before_ running the timers.
+
+### `clock.setSystemTime([now])`
+
+This simulates a user changing the system clock while your program is running.
+It affects the current time but it does not in itself cause e.g. timers to fire;
+they will fire exactly as they would have done without the call to
+setSystemTime().
+
+### `clock.uninstall()`
+
+Restores the original methods of the native timers or the methods on the object
+that was passed to `FakeTimers.withGlobal`
+
+### `Date`
+
+Implements the `Date` object but using the clock to provide the correct time.
+
+### `Performance`
+
+Implements the `now` method of the [`Performance`](https://developer.mozilla.org/en-US/docs/Web/API/Performance/now) object but using the clock to provide the correct time. Only available in environments that support the Performance object (browsers mostly).
+
+### `FakeTimers.withGlobal`
+
+In order to support creating clocks based on separate or sandboxed environments (such as JSDOM), FakeTimers exports a factory method which takes single argument `global`, which it inspects to figure out what to mock and what features to support. When invoking this function with a global, you will get back an object with `timers`, `createClock` and `install` - same as the regular FakeTimers exports only based on the passed in global instead of the global environment.
+
+## Running tests
+
+FakeTimers has a comprehensive test suite. If you're thinking of contributing bug
+fixes or suggesting new features, you need to make sure you have not broken any
+tests. You are also expected to add tests for any new behavior.
+
+### On node:
+
+```sh
+npm test
+```
+
+Or, if you prefer more verbose output:
+
+```
+$(npm bin)/mocha ./test/fake-timers-test.js
+```
+
+### In the browser
+
+[Mochify](https://github.com/mantoni/mochify.js) is used to run the tests in
+PhantomJS. Make sure you have `phantomjs` installed. Then:
+
+```sh
+npm test-headless
+```

+A. HISTORY OF THE SOFTWARE
+==========================
+
+Python was created in the early 1990s by Guido van Rossum at Stichting
+Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
+as a successor of a language called ABC.  Guido remains Python's
+principal author, although it includes many contributions from others.
+
+In 1995, Guido continued his work on Python at the Corporation for
+National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
+in Reston, Virginia where he released several versions of the
+software.
+
+In May 2000, Guido and the Python core development team moved to
+BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
+year, the PythonLabs team moved to Digital Creations, which became
+Zope Corporation.  In 2001, the Python Software Foundation (PSF, see
+https://www.python.org/psf/) was formed, a non-profit organization
+created specifically to own Python-related Intellectual Property.
+Zope Corporation was a sponsoring member of the PSF.
+
+All Python releases are Open Source (see http://www.opensource.org for
+the Open Source Definition).  Historically, most, but not all, Python
+releases have also been GPL-compatible; the table below summarizes
+the various releases.
+
+    Release         Derived     Year        Owner       GPL-
+                    from                                compatible? (1)
+
+    0.9.0 thru 1.2              1991-1995   CWI         yes
+    1.3 thru 1.5.2  1.2         1995-1999   CNRI        yes

+    1.6.1           1.6         2001        CNRI        yes (2)
+    2.1             2.0+1.6.1   2001        PSF         no

+    2.1.1           2.1+2.0.1   2001        PSF         yes
+    2.1.2           2.1.1       2002        PSF         yes
+    2.1.3           2.1.2       2002        PSF         yes
+    2.2 and above   2.1.1       2001-now    PSF         yes
+
+Footnotes:
+
+(1) GPL-compatible doesn't mean that we're distributing Python under
+    the GPL.  All Python licenses, unlike the GPL, let you distribute
+    a modified version without making your changes open source.  The
+    GPL-compatible licenses make it possible to combine Python with
+    other software that is released under the GPL; the others don't.
+
+(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
+    because its license has a choice of law clause.  According to
+    CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
+    is "not incompatible" with the GPL.
+
+Thanks to the many outside volunteers who have worked under Guido's
+direction to make these releases possible.

-**NB. Difference with original.**
+**Difference with original.**
 
-- Method names changed to camelCase. See [generated docs](http://nodeca.github.com/argparse/).
-- Use `defaultValue` instead of `default`.
-- Use `argparse.Const.REMAINDER` instead of `argparse.REMAINDER`, and
-  similarly for constant values `OPTIONAL`, `ZERO_OR_MORE`, and `ONE_OR_MORE`
-  (aliases for `nargs` values `'?'`, `'*'`, `'+'`, respectively), and
-  `SUPPRESS`.
+- JS has no keyword arguments support.
+  -  Pass options instead: `new ArgumentParser({ description: 'example', add_help: true })`.
+- JS has no python's types `int`, `float`, ...
+  - Use string-typed names: `.add_argument('-b', { type: 'int', help: 'help' })`.
+- `%r` format specifier uses `require('util').inspect()`.

-ArgumentParser objects
-======================
-
-```
-new ArgumentParser({parameters hash});
-```
-
-Creates a new ArgumentParser object.
-
-**Supported params:**
-
-- ```description``` - Text to display before the argument help.
-- ```epilog``` - Text to display after the argument help.
-- ```addHelp``` - Add a -h/–help option to the parser. (default: true)
-- ```argumentDefault``` - Set the global default value for arguments. (default: null)
-- ```parents``` - A list of ArgumentParser objects whose arguments should also be included.
-- ```prefixChars``` - The set of characters that prefix optional arguments. (default: ‘-‘)
-- ```formatterClass``` - A class for customizing the help output.
-- ```prog``` - The name of the program (default: `path.basename(process.argv[1])`)
-- ```usage``` - The string describing the program usage (default: generated)
-- ```conflictHandler``` - Usually unnecessary, defines strategy for resolving conflicting optionals.
-
-**Not supported yet**
-
-- ```fromfilePrefixChars``` - The set of characters that prefix files from which additional arguments should be read.
-
-
-Details in [original ArgumentParser guide](http://docs.python.org/dev/library/argparse.html#argumentparser-objects)
-
-
-addArgument() method
-====================
-
-```
-ArgumentParser.addArgument(name or flag or [name] or [flags...], {options})
-```
-
-Defines how a single command-line argument should be parsed.
-
-- ```name or flag or [name] or [flags...]``` - Either a positional name
-  (e.g., `'foo'`), a single option (e.g., `'-f'` or `'--foo'`), an array
-  of a single positional name (e.g., `['foo']`), or an array of options
-  (e.g., `['-f', '--foo']`).
-
-Options:
-
-- ```action``` - The basic type of action to be taken when this argument is encountered at the command line.
-- ```nargs```- The number of command-line arguments that should be consumed.
-- ```constant``` - A constant value required by some action and nargs selections.
-- ```defaultValue``` - The value produced if the argument is absent from the command line.
-- ```type``` - The type to which the command-line argument should be converted.
-- ```choices``` - A container of the allowable values for the argument.
-- ```required``` - Whether or not the command-line option may be omitted (optionals only).
-- ```help``` - A brief description of what the argument does.
-- ```metavar``` - A name for the argument in usage messages.
-- ```dest``` - The name of the attribute to be added to the object returned by parseArgs().
-
-Details in [original add_argument guide](http://docs.python.org/dev/library/argparse.html#the-add-argument-method)
-
-
-Action (some details)
-================
-
-ArgumentParser objects associate command-line arguments with actions.
-These actions can do just about anything with the command-line arguments associated
-with them, though most actions simply add an attribute to the object returned by
-parseArgs(). The action keyword argument specifies how the command-line arguments
-should be handled. The supported actions are:
-
-- ```store``` - Just stores the argument’s value. This is the default action.
-- ```storeConst``` - Stores value, specified by the const keyword argument.
-  (Note that the const keyword argument defaults to the rather unhelpful None.)
-  The 'storeConst' action is most commonly used with optional arguments, that
-  specify some sort of flag.
-- ```storeTrue``` and ```storeFalse``` - Stores values True and False
-  respectively. These are special cases of 'storeConst'.
-- ```append``` - Stores a list, and appends each argument value to the list.
-  This is useful to allow an option to be specified multiple times.
-- ```appendConst``` - Stores a list, and appends value, specified by the
-  const keyword argument to the list. (Note, that the const keyword argument defaults
-  is None.) The 'appendConst' action is typically used when multiple arguments need
-  to store constants to the same list.
-- ```count``` - Counts the number of times a keyword argument occurs. For example,
-  used for increasing verbosity levels.
-- ```help``` - Prints a complete help message for all the options in the current
-  parser and then exits. By default a help action is automatically added to the parser.
-  See ArgumentParser for details of how the output is created.
-- ```version``` - Prints version information and exit. Expects a `version=`
-  keyword argument in the addArgument() call.

-Sub-commands
-============
-
-ArgumentParser.addSubparsers()
-
-Many programs split their functionality into a number of sub-commands, for
-example, the svn program can invoke sub-commands like `svn checkout`, `svn update`,
-and `svn commit`. Splitting up functionality this way can be a particularly good
-idea when a program performs several different functions which require different
-kinds of command-line arguments. `ArgumentParser` supports creation of such
-sub-commands with `addSubparsers()` method. The `addSubparsers()` method is
-normally called with no arguments and returns an special action object.
-This object has a single method `addParser()`, which takes a command name and
-any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object
-that can be modified as usual.
-
-Example:
-
-sub_commands.js
-```javascript
-#!/usr/bin/env node
-'use strict';
-
-var ArgumentParser = require('../lib/argparse').ArgumentParser;
-var parser = new ArgumentParser({
-  version: '0.0.1',
-  addHelp:true,
-  description: 'Argparse examples: sub-commands',
-});
-
-var subparsers = parser.addSubparsers({
-  title:'subcommands',
-  dest:"subcommand_name"
-});
-
-var bar = subparsers.addParser('c1', {addHelp:true});
-bar.addArgument(
-  [ '-f', '--foo' ],
-  {
-    action: 'store',
-    help: 'foo3 bar3'
-  }
-);
-var bar = subparsers.addParser(
-  'c2',
-  {aliases:['co'], addHelp:true}
-);
-bar.addArgument(
-  [ '-b', '--bar' ],
-  {
-    action: 'store',
-    type: 'int',
-    help: 'foo3 bar3'
-  }
-);
-
-var args = parser.parseArgs();
-console.dir(args);
-
-```

+/*
+ * Command-line parsing library
+ *
+ * This module is an optparse-inspired command-line parsing library that:
+ *
+ *     - handles both optional and positional arguments
+ *     - produces highly informative usage messages
+ *     - supports parsers that dispatch to sub-parsers
+ *
+ * The following is a simple usage example that sums integers from the
+ * command-line and writes the result to a file::
+ *
+ *     parser = argparse.ArgumentParser(
+ *         description='sum the integers at the command line')
+ *     parser.add_argument(
+ *         'integers', metavar='int', nargs='+', type=int,
+ *         help='an integer to be summed')
+ *     parser.add_argument(
+ *         '--log', default=sys.stdout, type=argparse.FileType('w'),
+ *         help='the file where the sum should be written')
+ *     args = parser.parse_args()
+ *     args.log.write('%s' % sum(args.integers))
+ *     args.log.close()
+ *
+ * The module contains the following public classes:
+ *
+ *     - ArgumentParser -- The main entry point for command-line parsing. As the
+ *         example above shows, the add_argument() method is used to populate
+ *         the parser with actions for optional and positional arguments. Then
+ *         the parse_args() method is invoked to convert the args at the
+ *         command-line into an object with attributes.
+ *
+ *     - ArgumentError -- The exception raised by ArgumentParser objects when
+ *         there are errors with the parser's actions. Errors raised while
+ *         parsing the command-line are caught by ArgumentParser and emitted
+ *         as command-line messages.
+ *
+ *     - FileType -- A factory for defining types of files to be created. As the
+ *         example above shows, instances of FileType are typically passed as
+ *         the type= argument of add_argument() calls.
+ *
+ *     - Action -- The base class for parser actions. Typically actions are
+ *         selected by passing strings like 'store_true' or 'append_const' to
+ *         the action= argument of add_argument(). However, for greater
+ *         customization of ArgumentParser actions, subclasses of Action may
+ *         be defined and passed as the action= argument.
+ *
+ *     - HelpFormatter, RawDescriptionHelpFormatter, RawTextHelpFormatter,
+ *         ArgumentDefaultsHelpFormatter -- Formatter classes which
+ *         may be passed as the formatter_class= argument to the
+ *         ArgumentParser constructor. HelpFormatter is the default,
+ *         RawDescriptionHelpFormatter and RawTextHelpFormatter tell the parser
+ *         not to change the formatting for help text, and
+ *         ArgumentDefaultsHelpFormatter adds information about argument defaults
+ *         to the help.
+ *
+ * All other classes in this module are considered implementation details.
+ * (Also note that HelpFormatter and RawDescriptionHelpFormatter are only
+ * considered public as object names -- the API of the formatter objects is
+ * still considered an implementation detail.)

+     *  If you want to completely replace the main wrapping algorithm,

+     *  Several instance attributes control various aspects of wrapping:
+     *    width (default: 70)
+     *      the maximum width of wrapped lines (unless break_long_words
+     *      is false)
+     *    initial_indent (default: "")
+     *      string that will be prepended to the first line of wrapped
+     *      output.  Counts towards the line's width.
+     *    subsequent_indent (default: "")
+     *      string that will be prepended to all lines save the first
+     *      of wrapped output; also counts towards each line's width.
+     *    expand_tabs (default: true)
+     *      Expand tabs in input text to spaces before further processing.
+     *      Each tab will become 0 .. 'tabsize' spaces, depending on its position
+     *      in its line.  If false, each tab is treated as a single character.
+     *    tabsize (default: 8)
+     *      Expand tabs in input text to 0 .. 'tabsize' spaces, unless
+     *      'expand_tabs' is false.
+     *    replace_whitespace (default: true)
+     *      Replace all whitespace characters in the input text by spaces
+     *      after tab expansion.  Note that if expand_tabs is false and
+     *      replace_whitespace is true, every tab will be converted to a
+     *      single space!
+     *    fix_sentence_endings (default: false)
+     *      Ensure that sentence-ending punctuation is always followed
+     *      by two spaces.  Off by default because the algorithm is
+     *      (unavoidably) imperfect.
+     *    break_long_words (default: true)
+     *      Break words longer than 'width'.  If false, those words will not
+     *      be broken, and some lines might be longer than 'width'.
+     *    break_on_hyphens (default: true)
+     *      Allow breaking hyphenated words. If true, wrapping will occur
+     *      preferably on whitespaces and right after hyphens part of
+     *      compound words.

+
+[![Build Status](https://secure.travis-ci.org/nodeca/argparse.svg?branch=master)](http://travis-ci.org/nodeca/argparse)
+[![NPM version](https://img.shields.io/npm/v/argparse.svg)](https://www.npmjs.org/package/argparse)
+
+CLI arguments parser for node.js. Javascript port of python's
+[argparse](http://docs.python.org/dev/library/argparse.html) module
+(original version 3.2). That's a full port, except some very rare options,
+recorded in issue tracker.
+
+**NB. Difference with original.**
+
+- Method names changed to camelCase. See [generated docs](http://nodeca.github.com/argparse/).
+- Use `defaultValue` instead of `default`.
+- Use `argparse.Const.REMAINDER` instead of `argparse.REMAINDER`, and
+  similarly for constant values `OPTIONAL`, `ZERO_OR_MORE`, and `ONE_OR_MORE`
+  (aliases for `nargs` values `'?'`, `'*'`, `'+'`, respectively), and
+  `SUPPRESS`.
+
+
+Example
+=======
+
+test.js file:
+
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse example'
+});
+parser.addArgument(
+  [ '-f', '--foo' ],
+  {
+    help: 'foo bar'
+  }
+);
+parser.addArgument(
+  [ '-b', '--bar' ],
+  {
+    help: 'bar foo'
+  }
+);
+parser.addArgument(
+  '--baz',
+  {
+    help: 'baz bar'
+  }
+);
+var args = parser.parseArgs();
+console.dir(args);
+```
+
+Display help:
+
+```
+$ ./test.js -h
+usage: example.js [-h] [-v] [-f FOO] [-b BAR] [--baz BAZ]
+
+Argparse example
+
+Optional arguments:
+  -h, --help         Show this help message and exit.
+  -v, --version      Show program's version number and exit.
+  -f FOO, --foo FOO  foo bar
+  -b BAR, --bar BAR  bar foo
+  --baz BAZ          baz bar
+```
+
+Parse arguments:
+
+```
+$ ./test.js -f=3 --bar=4 --baz 5
+{ foo: '3', bar: '4', baz: '5' }
+```
+
+More [examples](https://github.com/nodeca/argparse/tree/master/examples).
+
+
+ArgumentParser objects
+======================
+
+```
+new ArgumentParser({parameters hash});
+```
+
+Creates a new ArgumentParser object.
+
+**Supported params:**
+
+- ```description``` - Text to display before the argument help.
+- ```epilog``` - Text to display after the argument help.
+- ```addHelp``` - Add a -h/–help option to the parser. (default: true)
+- ```argumentDefault``` - Set the global default value for arguments. (default: null)
+- ```parents``` - A list of ArgumentParser objects whose arguments should also be included.
+- ```prefixChars``` - The set of characters that prefix optional arguments. (default: ‘-‘)
+- ```formatterClass``` - A class for customizing the help output.
+- ```prog``` - The name of the program (default: `path.basename(process.argv[1])`)
+- ```usage``` - The string describing the program usage (default: generated)
+- ```conflictHandler``` - Usually unnecessary, defines strategy for resolving conflicting optionals.
+
+**Not supported yet**
+
+- ```fromfilePrefixChars``` - The set of characters that prefix files from which additional arguments should be read.
+
+
+Details in [original ArgumentParser guide](http://docs.python.org/dev/library/argparse.html#argumentparser-objects)
+
+
+addArgument() method
+====================
+
+```
+ArgumentParser.addArgument(name or flag or [name] or [flags...], {options})
+```
+
+Defines how a single command-line argument should be parsed.
+
+- ```name or flag or [name] or [flags...]``` - Either a positional name
+  (e.g., `'foo'`), a single option (e.g., `'-f'` or `'--foo'`), an array
+  of a single positional name (e.g., `['foo']`), or an array of options
+  (e.g., `['-f', '--foo']`).
+
+Options:
+
+- ```action``` - The basic type of action to be taken when this argument is encountered at the command line.
+- ```nargs```- The number of command-line arguments that should be consumed.
+- ```constant``` - A constant value required by some action and nargs selections.
+- ```defaultValue``` - The value produced if the argument is absent from the command line.
+- ```type``` - The type to which the command-line argument should be converted.
+- ```choices``` - A container of the allowable values for the argument.
+- ```required``` - Whether or not the command-line option may be omitted (optionals only).
+- ```help``` - A brief description of what the argument does.
+- ```metavar``` - A name for the argument in usage messages.
+- ```dest``` - The name of the attribute to be added to the object returned by parseArgs().
+
+Details in [original add_argument guide](http://docs.python.org/dev/library/argparse.html#the-add-argument-method)
+
+
+Action (some details)
+================
+
+ArgumentParser objects associate command-line arguments with actions.
+These actions can do just about anything with the command-line arguments associated
+with them, though most actions simply add an attribute to the object returned by
+parseArgs(). The action keyword argument specifies how the command-line arguments
+should be handled. The supported actions are:
+
+- ```store``` - Just stores the argument’s value. This is the default action.
+- ```storeConst``` - Stores value, specified by the const keyword argument.
+  (Note that the const keyword argument defaults to the rather unhelpful None.)
+  The 'storeConst' action is most commonly used with optional arguments, that
+  specify some sort of flag.
+- ```storeTrue``` and ```storeFalse``` - Stores values True and False
+  respectively. These are special cases of 'storeConst'.
+- ```append``` - Stores a list, and appends each argument value to the list.
+  This is useful to allow an option to be specified multiple times.
+- ```appendConst``` - Stores a list, and appends value, specified by the
+  const keyword argument to the list. (Note, that the const keyword argument defaults
+  is None.) The 'appendConst' action is typically used when multiple arguments need
+  to store constants to the same list.
+- ```count``` - Counts the number of times a keyword argument occurs. For example,
+  used for increasing verbosity levels.
+- ```help``` - Prints a complete help message for all the options in the current
+  parser and then exits. By default a help action is automatically added to the parser.
+  See ArgumentParser for details of how the output is created.
+- ```version``` - Prints version information and exit. Expects a `version=`
+  keyword argument in the addArgument() call.
+
+Details in [original action guide](http://docs.python.org/dev/library/argparse.html#action)
+
+
+Sub-commands
+============
+
+ArgumentParser.addSubparsers()
+
+Many programs split their functionality into a number of sub-commands, for
+example, the svn program can invoke sub-commands like `svn checkout`, `svn update`,
+and `svn commit`. Splitting up functionality this way can be a particularly good
+idea when a program performs several different functions which require different
+kinds of command-line arguments. `ArgumentParser` supports creation of such
+sub-commands with `addSubparsers()` method. The `addSubparsers()` method is
+normally called with no arguments and returns an special action object.
+This object has a single method `addParser()`, which takes a command name and
+any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object
+that can be modified as usual.
+
+Example:
+
+sub_commands.js
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse examples: sub-commands',
+});
+
+var subparsers = parser.addSubparsers({
+  title:'subcommands',
+  dest:"subcommand_name"
+});
+
+var bar = subparsers.addParser('c1', {addHelp:true});
+bar.addArgument(
+  [ '-f', '--foo' ],
+  {
+    action: 'store',
+    help: 'foo3 bar3'
+  }
+);
+var bar = subparsers.addParser(
+  'c2',
+  {aliases:['co'], addHelp:true}
+);
+bar.addArgument(
+  [ '-b', '--bar' ],
+  {
+    action: 'store',
+    type: 'int',
+    help: 'foo3 bar3'
+  }
+);
+
+var args = parser.parseArgs();
+console.dir(args);
+
+```

+ * - `constant`  Default value for an action with no value.
+ * - `defaultValue`  The value to be produced if the option is not specified.
+ * - `type`  Cast to 'string'|'int'|'float'|'complex'|function (string). If
+ * None, 'string'.
+ * - `choices`  The choices available.
+ * - `required`  True if the action must always be specified at the command
+ * line.

+JS-YAML - YAML 1.2 parser / writer for JavaScript
+=================================================
+
+[![Build Status](https://travis-ci.org/nodeca/js-yaml.svg?branch=master)](https://travis-ci.org/nodeca/js-yaml)
+[![NPM version](https://img.shields.io/npm/v/js-yaml.svg)](https://www.npmjs.org/package/js-yaml)
+
+__[Online Demo](http://nodeca.github.com/js-yaml/)__
+
+
+This is an implementation of [YAML](http://yaml.org/), a human-friendly data
+serialization language. Started as [PyYAML](http://pyyaml.org/) port, it was
+completely rewritten from scratch. Now it's very fast, and supports 1.2 spec.
+
+
+Installation
+------------
+
+### YAML module for node.js
+
+```
+npm install js-yaml
+```
+
+
+### CLI executable
+
+If you want to inspect your YAML files from CLI, install js-yaml globally:
+
+```
+npm install -g js-yaml
+```
+
+#### Usage
+
+```
+usage: js-yaml [-h] [-v] [-c] [-t] file
+
+Positional arguments:
+  file           File with YAML document(s)
+
+Optional arguments:
+  -h, --help     Show this help message and exit.
+  -v, --version  Show program's version number and exit.
+  -c, --compact  Display errors in compact mode
+  -t, --trace    Show stack trace on error
+```
+
+
+### Bundled YAML library for browsers
+
+``` html
+<!-- esprima required only for !!js/function -->
+<script src="esprima.js"></script>
+<script src="js-yaml.min.js"></script>
+<script type="text/javascript">
+var doc = jsyaml.load('greeting: hello\nname: world');
+</script>
+```
+
+Browser support was done mostly for the online demo. If you find any errors - feel
+free to send pull requests with fixes. Also note, that IE and other old browsers
+needs [es5-shims](https://github.com/kriskowal/es5-shim) to operate.
+
+Notes:
+
+1. We have no resources to support browserified version. Don't expect it to be
+   well tested. Don't expect fast fixes if something goes wrong there.
+2. `!!js/function` in browser bundle will not work by default. If you really need
+   it - load `esprima` parser first (via amd or directly).
+3. `!!bin` in browser will return `Array`, because browsers do not support
+   node.js `Buffer` and adding Buffer shims is completely useless on practice.
+
+
+API
+---
+
+Here we cover the most 'useful' methods. If you need advanced details (creating
+your own tags), see [wiki](https://github.com/nodeca/js-yaml/wiki) and
+[examples](https://github.com/nodeca/js-yaml/tree/master/examples) for more
+info.
+
+``` javascript
+const yaml = require('js-yaml');
+const fs   = require('fs');
+
+// Get document, or throw exception on error
+try {
+  const doc = yaml.safeLoad(fs.readFileSync('/home/ixti/example.yml', 'utf8'));
+  console.log(doc);
+} catch (e) {
+  console.log(e);
+}
+```
+
+
+### safeLoad (string [ , options ])
+
+**Recommended loading way.** Parses `string` as single YAML document. Returns either a
+plain object, a string or `undefined`, or throws `YAMLException` on error. By default, does
+not support regexps, functions and undefined. This method is safe for untrusted data.
+
+options:
+
+- `filename` _(default: null)_ - string to be used as a file path in
+  error/warning messages.
+- `onWarning` _(default: null)_ - function to call on warning messages.
+  Loader will call this function with an instance of `YAMLException` for each warning.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ - specifies a schema to use.
+  - `FAILSAFE_SCHEMA` - only strings, arrays and plain objects:
+    http://www.yaml.org/spec/1.2/spec.html#id2802346
+  - `JSON_SCHEMA` - all JSON-supported types:
+    http://www.yaml.org/spec/1.2/spec.html#id2803231
+  - `CORE_SCHEMA` - same as `JSON_SCHEMA`:
+    http://www.yaml.org/spec/1.2/spec.html#id2804923
+  - `DEFAULT_SAFE_SCHEMA` - all supported YAML types, without unsafe ones
+    (`!!js/undefined`, `!!js/regexp` and `!!js/function`):
+    http://yaml.org/type/
+  - `DEFAULT_FULL_SCHEMA` - all supported YAML types.
+- `json` _(default: false)_ - compatibility with JSON.parse behaviour. If true, then duplicate keys in a mapping will override values rather than throwing an error.
+
+NOTE: This function **does not** understand multi-document sources, it throws
+exception on those.
+
+NOTE: JS-YAML **does not** support schema-specific tag resolution restrictions.
+So, the JSON schema is not as strictly defined in the YAML specification.
+It allows numbers in any notation, use `Null` and `NULL` as `null`, etc.
+The core schema also has no such restrictions. It allows binary notation for integers.
+
+
+### load (string [ , options ])
+
+**Use with care with untrusted sources**. The same as `safeLoad()` but uses
+`DEFAULT_FULL_SCHEMA` by default - adds some JavaScript-specific types:
+`!!js/function`, `!!js/regexp` and `!!js/undefined`. For untrusted sources, you
+must additionally validate object structure to avoid injections:
+
+``` javascript
+const untrusted_code = '"toString": !<tag:yaml.org,2002:js/function> "function (){very_evil_thing();}"';
+
+// I'm just converting that string, what could possibly go wrong?
+require('js-yaml').load(untrusted_code) + ''
+```
+
+
+### safeLoadAll (string [, iterator] [, options ])
+
+Same as `safeLoad()`, but understands multi-document sources. Applies
+`iterator` to each document if specified, or returns array of documents.
+
+``` javascript
+const yaml = require('js-yaml');
+
+yaml.safeLoadAll(data, function (doc) {
+  console.log(doc);
+});
+```
+
+
+### loadAll (string [, iterator] [ , options ])
+
+Same as `safeLoadAll()` but uses `DEFAULT_FULL_SCHEMA` by default.
+
+
+### safeDump (object [ , options ])
+
+Serializes `object` as a YAML document. Uses `DEFAULT_SAFE_SCHEMA`, so it will
+throw an exception if you try to dump regexps or functions. However, you can
+disable exceptions by setting the `skipInvalid` option to `true`.
+
+options:
+
+- `indent` _(default: 2)_ - indentation width to use (in spaces).
+- `noArrayIndent` _(default: false)_ - when true, will not add an indentation level to array elements
+- `skipInvalid` _(default: false)_ - do not throw on invalid types (like function
+  in the safe schema) and skip pairs and single values with such types.
+- `flowLevel` (default: -1) - specifies level of nesting, when to switch from
+  block to flow style for collections. -1 means block style everwhere
+- `styles` - "tag" => "style" map. Each tag may have own set of styles.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ specifies a schema to use.
+- `sortKeys` _(default: `false`)_ - if `true`, sort keys when dumping YAML. If a
+  function, use the function to sort the keys.
+- `lineWidth` _(default: `80`)_ - set max line width.
+- `noRefs` _(default: `false`)_ - if `true`, don't convert duplicate objects into references
+- `noCompatMode` _(default: `false`)_ - if `true` don't try to be compatible with older
+  yaml versions. Currently: don't quote "yes", "no" and so on, as required for YAML 1.1
+- `condenseFlow` _(default: `false`)_ - if `true` flow sequences will be condensed, omitting the space between `a, b`. Eg. `'[a,b]'`, and omitting the space between `key: value` and quoting the key. Eg. `'{"a":b}'` Can be useful when using yaml for pretty URL query params as spaces are %-encoded.
+
+The following table show availlable styles (e.g. "canonical",
+"binary"...) available for each tag (.e.g. !!null, !!int ...). Yaml
+output is shown on the right side after `=>` (default setting) or `->`:
+
+``` none
+!!null
+  "canonical"   -> "~"
+  "lowercase"   => "null"
+  "uppercase"   -> "NULL"
+  "camelcase"   -> "Null"
+
+!!int
+  "binary"      -> "0b1", "0b101010", "0b1110001111010"
+  "octal"       -> "01", "052", "016172"
+  "decimal"     => "1", "42", "7290"
+  "hexadecimal" -> "0x1", "0x2A", "0x1C7A"
+
+!!bool
+  "lowercase"   => "true", "false"
+  "uppercase"   -> "TRUE", "FALSE"
+  "camelcase"   -> "True", "False"
+
+!!float
+  "lowercase"   => ".nan", '.inf'
+  "uppercase"   -> ".NAN", '.INF'
+  "camelcase"   -> ".NaN", '.Inf'
+```
+
+Example:
+
+``` javascript
+safeDump (object, {
+  'styles': {
+    '!!null': 'canonical' // dump null as ~
+  },
+  'sortKeys': true        // sort object keys
+});
+```
+
+### dump (object [ , options ])
+
+Same as `safeDump()` but without limits (uses `DEFAULT_FULL_SCHEMA` by default).
+
+
+Supported YAML types
+--------------------
+
+The list of standard YAML tags and corresponding JavaScipt types. See also
+[YAML tag discussion](http://pyyaml.org/wiki/YAMLTagDiscussion) and
+[YAML types repository](http://yaml.org/type/).
+
+```
+!!null ''                   # null
+!!bool 'yes'                # bool
+!!int '3...'                # number
+!!float '3.14...'           # number
+!!binary '...base64...'     # buffer
+!!timestamp 'YYYY-...'      # date
+!!omap [ ... ]              # array of key-value pairs
+!!pairs [ ... ]             # array or array pairs
+!!set { ... }               # array of objects with given keys and null values
+!!str '...'                 # string
+!!seq [ ... ]               # array
+!!map { ... }               # object
+```
+
+**JavaScript-specific tags**
+
+```
+!!js/regexp /pattern/gim            # RegExp
+!!js/undefined ''                   # Undefined
+!!js/function 'function () {...}'   # Function
+```
+
+Caveats
+-------
+
+Note, that you use arrays or objects as key in JS-YAML. JS does not allow objects
+or arrays as keys, and stringifies (by calling `toString()` method) them at the
+moment of adding them.
+
+``` yaml
+---
+? [ foo, bar ]
+: - baz
+? { foo: bar }
+: - baz
+  - baz
+```
+
+``` javascript
+{ "foo,bar": ["baz"], "[object Object]": ["baz", "baz"] }
+```
+
+Also, reading of properties on implicit block mapping keys is not supported yet.
+So, the following YAML document cannot be loaded.
+
+``` yaml
+&anchor foo:
+  foo: bar
+  *anchor: duplicate key
+  baz: bat
+  *anchor: duplicate key
+```

-3.13.1 / 2019-04-05
--------------------
-
+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+
+## [4.1.0] - 2021-04-15
+### Added
+- Types are now exported as `yaml.types.XXX`.
+- Every type now has `options` property with original arguments kept as they were
+  (see `yaml.types.int.options` as an example).
+
+### Changed
+- `Schema.extend()` now keeps old type order in case of conflicts
+  (e.g. Schema.extend([ a, b, c ]).extend([ b, a, d ]) is now ordered as `abcd` instead of `cbad`).
+
+
+## [4.0.0] - 2021-01-03
+### Changed
+- Check [migration guide](migrate_v3_to_v4.md) to see details for all breaking changes.
+- Breaking: "unsafe" tags `!!js/function`, `!!js/regexp`, `!!js/undefined` are
+  moved to [js-yaml-js-types](https://github.com/nodeca/js-yaml-js-types) package.
+- Breaking: removed `safe*` functions. Use `load`, `loadAll`, `dump`
+  instead which are all now safe by default.
+- `yaml.DEFAULT_SAFE_SCHEMA` and `yaml.DEFAULT_FULL_SCHEMA` are removed, use
+  `yaml.DEFAULT_SCHEMA` instead.
+- `yaml.Schema.create(schema, tags)` is removed, use `schema.extend(tags)` instead.
+- `!!binary` now always mapped to `Uint8Array` on load.
+- Reduced nesting of `/lib` folder.
+- Parse numbers according to YAML 1.2 instead of YAML 1.1 (`01234` is now decimal,
+  `0o1234` is octal, `1:23` is parsed as string instead of base60).
+- `dump()` no longer quotes `:`, `[`, `]`, `(`, `)` except when necessary, #470, #557.
+- Line and column in exceptions are now formatted as `(X:Y)` instead of
+  `at line X, column Y` (also present in compact format), #332.
+- Code snippet created in exceptions now contains multiple lines with line numbers.
+- `dump()` now serializes `undefined` as `null` in collections and removes keys with
+  `undefined` in mappings, #571.
+- `dump()` with `skipInvalid=true` now serializes invalid items in collections as null.
+- Custom tags starting with `!` are now dumped as `!tag` instead of `!<!tag>`, #576.
+- Custom tags starting with `tag:yaml.org,2002:` are now shorthanded using `!!`, #258.
+
+### Added
+- Added `.mjs` (es modules) support.
+- Added `quotingType` and `forceQuotes` options for dumper to configure
+  string literal style, #290, #529.
+- Added `styles: { '!!null': 'empty' }` option for dumper
+  (serializes `{ foo: null }` as "`foo: `"), #570.
+- Added `replacer` option (similar to option in JSON.stringify), #339.
+- Custom `Tag` can now handle all tags or multiple tags with the same prefix, #385.
+
+### Fixed
+- Astral characters are no longer encoded by `dump()`, #587.
+- "duplicate mapping key" exception now points at the correct column, #452.
+- Extra commas in flow collections (e.g. `[foo,,bar]`) now throw an exception
+  instead of producing null, #321.
+- `__proto__` key no longer overrides object prototype, #164.
+- Removed `bower.json`.
+- Tags are now url-decoded in `load()` and url-encoded in `dump()`
+  (previously usage of custom non-ascii tags may have led to invalid YAML that can't be parsed).
+- Anchors now work correctly with empty nodes, #301.
+- Fix incorrect parsing of invalid block mapping syntax, #418.
+- Throw an error if block sequence/mapping indent contains a tab, #80.
+
+
+## [3.14.1] - 2020-12-07
+### Security
+- Fix possible code execution in (already unsafe) `.load()` (in &anchor).
+
+

-
-1. We have no resources to support browserified version. Don't expect it to be

-2. `!!js/function` in browser bundle will not work by default. If you really need

-3. `!!bin` in browser will return `Array`, because browsers do not support

+
+CLI arguments parser for node.js. Javascript port of python's
+[argparse](http://docs.python.org/dev/library/argparse.html) module
+(original version 3.2). That's a full port, except some very rare options,
+recorded in issue tracker.
+
+**NB. Difference with original.**
+
+- Method names changed to camelCase. See [generated docs](http://nodeca.github.com/argparse/).
+- Use `defaultValue` instead of `default`.
+- Use `argparse.Const.REMAINDER` instead of `argparse.REMAINDER`, and
+  similarly for constant values `OPTIONAL`, `ZERO_OR_MORE`, and `ONE_OR_MORE`
+  (aliases for `nargs` values `'?'`, `'*'`, `'+'`, respectively), and
+  `SUPPRESS`.
+
+
+Example
+=======
+
+test.js file:
+
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse example'
+});
+parser.addArgument(
+  [ '-f', '--foo' ],
+  {
+    help: 'foo bar'
+  }
+);
+parser.addArgument(
+  [ '-b', '--bar' ],
+  {
+    help: 'bar foo'
+  }
+);
+parser.addArgument(
+  '--baz',
+  {
+    help: 'baz bar'
+  }
+);
+var args = parser.parseArgs();
+console.dir(args);
+```
+
+Display help:
+
+```
+$ ./test.js -h
+usage: example.js [-h] [-v] [-f FOO] [-b BAR] [--baz BAZ]
+
+Argparse example
+
+Optional arguments:
+  -h, --help         Show this help message and exit.
+  -v, --version      Show program's version number and exit.
+  -f FOO, --foo FOO  foo bar
+  -b BAR, --bar BAR  bar foo
+  --baz BAZ          baz bar
+```
+
+Parse arguments:
+
+```
+$ ./test.js -f=3 --bar=4 --baz 5
+{ foo: '3', bar: '4', baz: '5' }
+```
+
+More [examples](https://github.com/nodeca/argparse/tree/master/examples).
+
+
+ArgumentParser objects
+======================
+
+```
+new ArgumentParser({parameters hash});
+```
+
+Creates a new ArgumentParser object.
+
+**Supported params:**
+
+- ```description``` - Text to display before the argument help.
+- ```epilog``` - Text to display after the argument help.
+- ```addHelp``` - Add a -h/–help option to the parser. (default: true)
+- ```argumentDefault``` - Set the global default value for arguments. (default: null)
+- ```parents``` - A list of ArgumentParser objects whose arguments should also be included.
+- ```prefixChars``` - The set of characters that prefix optional arguments. (default: ‘-‘)
+- ```formatterClass``` - A class for customizing the help output.
+- ```prog``` - The name of the program (default: `path.basename(process.argv[1])`)
+- ```usage``` - The string describing the program usage (default: generated)
+- ```conflictHandler``` - Usually unnecessary, defines strategy for resolving conflicting optionals.
+
+**Not supported yet**
+
+- ```fromfilePrefixChars``` - The set of characters that prefix files from which additional arguments should be read.
+
+
+Details in [original ArgumentParser guide](http://docs.python.org/dev/library/argparse.html#argumentparser-objects)
+
+
+addArgument() method
+====================
+
+```
+ArgumentParser.addArgument(name or flag or [name] or [flags...], {options})
+```
+
+Defines how a single command-line argument should be parsed.
+
+- ```name or flag or [name] or [flags...]``` - Either a positional name
+  (e.g., `'foo'`), a single option (e.g., `'-f'` or `'--foo'`), an array
+  of a single positional name (e.g., `['foo']`), or an array of options
+  (e.g., `['-f', '--foo']`).
+
+Options:
+
+- ```action``` - The basic type of action to be taken when this argument is encountered at the command line.
+- ```nargs```- The number of command-line arguments that should be consumed.
+- ```constant``` - A constant value required by some action and nargs selections.
+- ```defaultValue``` - The value produced if the argument is absent from the command line.
+- ```type``` - The type to which the command-line argument should be converted.
+- ```choices``` - A container of the allowable values for the argument.
+- ```required``` - Whether or not the command-line option may be omitted (optionals only).
+- ```help``` - A brief description of what the argument does.
+- ```metavar``` - A name for the argument in usage messages.
+- ```dest``` - The name of the attribute to be added to the object returned by parseArgs().
+
+Details in [original add_argument guide](http://docs.python.org/dev/library/argparse.html#the-add-argument-method)
+
+
+Action (some details)
+================
+
+ArgumentParser objects associate command-line arguments with actions.
+These actions can do just about anything with the command-line arguments associated
+with them, though most actions simply add an attribute to the object returned by
+parseArgs(). The action keyword argument specifies how the command-line arguments
+should be handled. The supported actions are:
+
+- ```store``` - Just stores the argument’s value. This is the default action.
+- ```storeConst``` - Stores value, specified by the const keyword argument.
+  (Note that the const keyword argument defaults to the rather unhelpful None.)
+  The 'storeConst' action is most commonly used with optional arguments, that
+  specify some sort of flag.
+- ```storeTrue``` and ```storeFalse``` - Stores values True and False
+  respectively. These are special cases of 'storeConst'.
+- ```append``` - Stores a list, and appends each argument value to the list.
+  This is useful to allow an option to be specified multiple times.
+- ```appendConst``` - Stores a list, and appends value, specified by the
+  const keyword argument to the list. (Note, that the const keyword argument defaults
+  is None.) The 'appendConst' action is typically used when multiple arguments need
+  to store constants to the same list.
+- ```count``` - Counts the number of times a keyword argument occurs. For example,
+  used for increasing verbosity levels.
+- ```help``` - Prints a complete help message for all the options in the current
+  parser and then exits. By default a help action is automatically added to the parser.
+  See ArgumentParser for details of how the output is created.
+- ```version``` - Prints version information and exit. Expects a `version=`
+  keyword argument in the addArgument() call.
+
+Details in [original action guide](http://docs.python.org/dev/library/argparse.html#action)
+
+
+Sub-commands
+============
+
+ArgumentParser.addSubparsers()
+
+Many programs split their functionality into a number of sub-commands, for
+example, the svn program can invoke sub-commands like `svn checkout`, `svn update`,
+and `svn commit`. Splitting up functionality this way can be a particularly good
+idea when a program performs several different functions which require different
+kinds of command-line arguments. `ArgumentParser` supports creation of such
+sub-commands with `addSubparsers()` method. The `addSubparsers()` method is
+normally called with no arguments and returns an special action object.
+This object has a single method `addParser()`, which takes a command name and
+any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object
+that can be modified as usual.
+
+Example:
+
+sub_commands.js
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse examples: sub-commands',
+});
+
+var subparsers = parser.addSubparsers({
+  title:'subcommands',
+  dest:"subcommand_name"
+});
+
+var bar = subparsers.addParser('c1', {addHelp:true});
+bar.addArgument(
+  [ '-f', '--foo' ],
+  {
+    action: 'store',
+    help: 'foo3 bar3'
+  }
+);
+var bar = subparsers.addParser(
+  'c2',
+  {aliases:['co'], addHelp:true}
+);
+bar.addArgument(
+  [ '-b', '--bar' ],
+  {
+    action: 'store',
+    type: 'int',
+    help: 'foo3 bar3'
+  }
+);
+
+var args = parser.parseArgs();
+console.dir(args);
+
+```

+JS-YAML - YAML 1.2 parser / writer for JavaScript
+=================================================
+
+[![Build Status](https://travis-ci.org/nodeca/js-yaml.svg?branch=master)](https://travis-ci.org/nodeca/js-yaml)
+[![NPM version](https://img.shields.io/npm/v/js-yaml.svg)](https://www.npmjs.org/package/js-yaml)
+
+__[Online Demo](http://nodeca.github.com/js-yaml/)__
+
+
+This is an implementation of [YAML](http://yaml.org/), a human-friendly data
+serialization language. Started as [PyYAML](http://pyyaml.org/) port, it was
+completely rewritten from scratch. Now it's very fast, and supports 1.2 spec.
+
+
+Installation
+------------
+
+### YAML module for node.js
+
+```
+npm install js-yaml
+```
+
+
+### CLI executable
+
+If you want to inspect your YAML files from CLI, install js-yaml globally:
+
+```
+npm install -g js-yaml
+```
+
+#### Usage
+
+```
+usage: js-yaml [-h] [-v] [-c] [-t] file
+
+Positional arguments:
+  file           File with YAML document(s)
+
+Optional arguments:
+  -h, --help     Show this help message and exit.
+  -v, --version  Show program's version number and exit.
+  -c, --compact  Display errors in compact mode
+  -t, --trace    Show stack trace on error
+```
+
+
+### Bundled YAML library for browsers
+
+``` html
+<!-- esprima required only for !!js/function -->
+<script src="esprima.js"></script>
+<script src="js-yaml.min.js"></script>
+<script type="text/javascript">
+var doc = jsyaml.load('greeting: hello\nname: world');
+</script>
+```
+
+Browser support was done mostly for the online demo. If you find any errors - feel
+free to send pull requests with fixes. Also note, that IE and other old browsers
+needs [es5-shims](https://github.com/kriskowal/es5-shim) to operate.
+
+Notes:
+
+1. We have no resources to support browserified version. Don't expect it to be
+   well tested. Don't expect fast fixes if something goes wrong there.
+2. `!!js/function` in browser bundle will not work by default. If you really need
+   it - load `esprima` parser first (via amd or directly).
+3. `!!bin` in browser will return `Array`, because browsers do not support
+   node.js `Buffer` and adding Buffer shims is completely useless on practice.
+
+
+API
+---
+
+Here we cover the most 'useful' methods. If you need advanced details (creating
+your own tags), see [wiki](https://github.com/nodeca/js-yaml/wiki) and
+[examples](https://github.com/nodeca/js-yaml/tree/master/examples) for more
+info.
+
+``` javascript
+const yaml = require('js-yaml');
+const fs   = require('fs');
+
+// Get document, or throw exception on error
+try {
+  const doc = yaml.safeLoad(fs.readFileSync('/home/ixti/example.yml', 'utf8'));
+  console.log(doc);
+} catch (e) {
+  console.log(e);
+}
+```
+
+
+### safeLoad (string [ , options ])
+
+**Recommended loading way.** Parses `string` as single YAML document. Returns either a
+plain object, a string or `undefined`, or throws `YAMLException` on error. By default, does
+not support regexps, functions and undefined. This method is safe for untrusted data.
+
+options:
+
+- `filename` _(default: null)_ - string to be used as a file path in
+  error/warning messages.
+- `onWarning` _(default: null)_ - function to call on warning messages.
+  Loader will call this function with an instance of `YAMLException` for each warning.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ - specifies a schema to use.
+  - `FAILSAFE_SCHEMA` - only strings, arrays and plain objects:
+    http://www.yaml.org/spec/1.2/spec.html#id2802346
+  - `JSON_SCHEMA` - all JSON-supported types:
+    http://www.yaml.org/spec/1.2/spec.html#id2803231
+  - `CORE_SCHEMA` - same as `JSON_SCHEMA`:
+    http://www.yaml.org/spec/1.2/spec.html#id2804923
+  - `DEFAULT_SAFE_SCHEMA` - all supported YAML types, without unsafe ones
+    (`!!js/undefined`, `!!js/regexp` and `!!js/function`):
+    http://yaml.org/type/
+  - `DEFAULT_FULL_SCHEMA` - all supported YAML types.
+- `json` _(default: false)_ - compatibility with JSON.parse behaviour. If true, then duplicate keys in a mapping will override values rather than throwing an error.
+
+NOTE: This function **does not** understand multi-document sources, it throws
+exception on those.
+
+NOTE: JS-YAML **does not** support schema-specific tag resolution restrictions.
+So, the JSON schema is not as strictly defined in the YAML specification.
+It allows numbers in any notation, use `Null` and `NULL` as `null`, etc.
+The core schema also has no such restrictions. It allows binary notation for integers.
+
+
+### load (string [ , options ])
+
+**Use with care with untrusted sources**. The same as `safeLoad()` but uses
+`DEFAULT_FULL_SCHEMA` by default - adds some JavaScript-specific types:
+`!!js/function`, `!!js/regexp` and `!!js/undefined`. For untrusted sources, you
+must additionally validate object structure to avoid injections:
+
+``` javascript
+const untrusted_code = '"toString": !<tag:yaml.org,2002:js/function> "function (){very_evil_thing();}"';
+
+// I'm just converting that string, what could possibly go wrong?
+require('js-yaml').load(untrusted_code) + ''
+```
+
+
+### safeLoadAll (string [, iterator] [, options ])
+
+Same as `safeLoad()`, but understands multi-document sources. Applies
+`iterator` to each document if specified, or returns array of documents.
+
+``` javascript
+const yaml = require('js-yaml');
+
+yaml.safeLoadAll(data, function (doc) {
+  console.log(doc);
+});
+```
+
+
+### loadAll (string [, iterator] [ , options ])
+
+Same as `safeLoadAll()` but uses `DEFAULT_FULL_SCHEMA` by default.
+
+
+### safeDump (object [ , options ])
+
+Serializes `object` as a YAML document. Uses `DEFAULT_SAFE_SCHEMA`, so it will
+throw an exception if you try to dump regexps or functions. However, you can
+disable exceptions by setting the `skipInvalid` option to `true`.
+
+options:
+
+- `indent` _(default: 2)_ - indentation width to use (in spaces).
+- `noArrayIndent` _(default: false)_ - when true, will not add an indentation level to array elements
+- `skipInvalid` _(default: false)_ - do not throw on invalid types (like function
+  in the safe schema) and skip pairs and single values with such types.
+- `flowLevel` (default: -1) - specifies level of nesting, when to switch from
+  block to flow style for collections. -1 means block style everwhere
+- `styles` - "tag" => "style" map. Each tag may have own set of styles.
+- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ specifies a schema to use.
+- `sortKeys` _(default: `false`)_ - if `true`, sort keys when dumping YAML. If a
+  function, use the function to sort the keys.
+- `lineWidth` _(default: `80`)_ - set max line width.
+- `noRefs` _(default: `false`)_ - if `true`, don't convert duplicate objects into references
+- `noCompatMode` _(default: `false`)_ - if `true` don't try to be compatible with older
+  yaml versions. Currently: don't quote "yes", "no" and so on, as required for YAML 1.1
+- `condenseFlow` _(default: `false`)_ - if `true` flow sequences will be condensed, omitting the space between `a, b`. Eg. `'[a,b]'`, and omitting the space between `key: value` and quoting the key. Eg. `'{"a":b}'` Can be useful when using yaml for pretty URL query params as spaces are %-encoded.
+
+The following table show availlable styles (e.g. "canonical",
+"binary"...) available for each tag (.e.g. !!null, !!int ...). Yaml
+output is shown on the right side after `=>` (default setting) or `->`:
+
+``` none
+!!null
+  "canonical"   -> "~"
+  "lowercase"   => "null"
+  "uppercase"   -> "NULL"
+  "camelcase"   -> "Null"
+
+!!int
+  "binary"      -> "0b1", "0b101010", "0b1110001111010"
+  "octal"       -> "01", "052", "016172"
+  "decimal"     => "1", "42", "7290"
+  "hexadecimal" -> "0x1", "0x2A", "0x1C7A"
+
+!!bool
+  "lowercase"   => "true", "false"
+  "uppercase"   -> "TRUE", "FALSE"
+  "camelcase"   -> "True", "False"
+
+!!float
+  "lowercase"   => ".nan", '.inf'
+  "uppercase"   -> ".NAN", '.INF'
+  "camelcase"   -> ".NaN", '.Inf'
+```
+
+Example:
+
+``` javascript
+safeDump (object, {
+  'styles': {
+    '!!null': 'canonical' // dump null as ~
+  },
+  'sortKeys': true        // sort object keys
+});
+```
+
+### dump (object [ , options ])
+
+Same as `safeDump()` but without limits (uses `DEFAULT_FULL_SCHEMA` by default).
+
+
+Supported YAML types
+--------------------
+
+The list of standard YAML tags and corresponding JavaScipt types. See also
+[YAML tag discussion](http://pyyaml.org/wiki/YAMLTagDiscussion) and
+[YAML types repository](http://yaml.org/type/).
+
+```
+!!null ''                   # null
+!!bool 'yes'                # bool
+!!int '3...'                # number
+!!float '3.14...'           # number
+!!binary '...base64...'     # buffer
+!!timestamp 'YYYY-...'      # date
+!!omap [ ... ]              # array of key-value pairs
+!!pairs [ ... ]             # array or array pairs
+!!set { ... }               # array of objects with given keys and null values
+!!str '...'                 # string
+!!seq [ ... ]               # array
+!!map { ... }               # object
+```
+
+**JavaScript-specific tags**
+
+```
+!!js/regexp /pattern/gim            # RegExp
+!!js/undefined ''                   # Undefined
+!!js/function 'function () {...}'   # Function
+```
+
+Caveats
+-------
+
+Note, that you use arrays or objects as key in JS-YAML. JS does not allow objects
+or arrays as keys, and stringifies (by calling `toString()` method) them at the
+moment of adding them.
+
+``` yaml
+---
+? [ foo, bar ]
+: - baz
+? { foo: bar }
+: - baz
+  - baz
+```
+
+``` javascript
+{ "foo,bar": ["baz"], "[object Object]": ["baz", "baz"] }
+```
+
+Also, reading of properties on implicit block mapping keys is not supported yet.
+So, the following YAML document cannot be loaded.
+
+``` yaml
+&anchor foo:
+  foo: bar
+  *anchor: duplicate key
+  baz: bat
+  *anchor: duplicate key
+```
