-
-
-The mighty option parser used by [yargs](https://github.com/yargs/yargs).
-
-visit the [yargs website](http://yargs.js.org/) for more examples, and thorough usage instructions.

-
-## Example
-
-```sh
-npm i yargs-parser --save
-```
-
-```js
-var argv = require('yargs-parser')(process.argv.slice(2))
-console.log(argv)
-```
-
-```sh
-node example.js --foo=33 --bar hello
-{ _: [], foo: 33, bar: 'hello' }
-```
-
-_or parse a string!_
-
-```js
-var argv = require('./')('--foo=99 --bar=33')
-console.log(argv)
-```
-
-```sh
-{ _: [], foo: 99, bar: 33 }
-```
-
-Convert an array of mixed types before passing to `yargs-parser`:
-
-```js
-var parse = require('yargs-parser')
-parse(['-f', 11, '--zoom', 55].join(' ')) // <-- array to string
-parse(['-f', 11, '--zoom', 55].map(String)) // <-- array of strings
-```
-
-## API
-
-### require('yargs-parser')(args, opts={})
-
-Parses command line arguments returning a simple mapping of keys and values.
-
-**expects:**
-
-* `args`: a string or array of strings representing the options to parse.
-* `opts`: provide a set of hints indicating how `args` should be parsed:
- * `opts.alias`: an object representing the set of aliases for a key: `{alias: {foo: ['f']}}`.
- * `opts.array`: indicate that keys should be parsed as an array: `{array: ['foo', 'bar']}`.
- * `opts.boolean`: arguments should be parsed as booleans: `{boolean: ['x', 'y']}`.
- * `opts.config`: indicate a key that represents a path to a configuration file (this file will be loaded and parsed).
- * `opts.coerce`: provide a custom synchronous function that returns a coerced value from the argument provided
- (or throws an error), e.g. `{coerce: {foo: function (arg) {return modifiedArg}}}`.
- * `opts.count`: indicate a key that should be used as a counter, e.g., `-vvv` = `{v: 3}`.
- * `opts.default`: provide default values for keys: `{default: {x: 33, y: 'hello world!'}}`.
- * `opts.envPrefix`: environment variables (`process.env`) with the prefix provided should be parsed.
- * `opts.narg`: specify that a key requires `n` arguments: `{narg: {x: 2}}`.
- * `opts.normalize`: `path.normalize()` will be applied to values set to this key.
- * `opts.string`: keys should be treated as strings (even if they resemble a number `-x 33`).
- * `opts.configuration`: provide configuration options to the yargs-parser (see: [configuration](#configuration)).
- * `opts.number`: keys should be treated as numbers.
- * `opts['--']`: arguments after the end-of-options flag `--` will be set to the `argv.['--']` array instead of being set to the `argv._` array.
-
-**returns:**
-
-* `obj`: an object representing the parsed value of `args`
- * `key/value`: key value pairs for each argument and their aliases.
- * `_`: an array representing the positional arguments.
- * [optional] `--`: an array with arguments after the end-of-options flag `--`.
-
-### require('yargs-parser').detailed(args, opts={})
-
-Parses a command line string, returning detailed information required by the
-yargs engine.
-
-**expects:**
-
-* `args`: a string or array of strings representing options to parse.
-* `opts`: provide a set of hints indicating how `args`, inputs are identical to `require('yargs-parser')(args, opts={})`.
-
-**returns:**
-
-* `argv`: an object representing the parsed value of `args`
- * `key/value`: key value pairs for each argument and their aliases.
- * `_`: an array representing the positional arguments.
-* `error`: populated with an error object if an exception occurred during parsing.
-* `aliases`: the inferred list of aliases built by combining lists in `opts.alias`.
-* `newAliases`: any new aliases added via camel-case expansion.
-* `configuration`: the configuration loaded from the `yargs` stanza in package.json.

-
-### Configuration
-
-The yargs-parser applies several automated transformations on the keys provided
-in `args`. These features can be turned on and off using the `configuration` field
-of `opts`.
-
-```js
-var parsed = parser(['--no-dice'], {
- configuration: {
- 'boolean-negation': false
- }
-})
-```
-
-### short option groups
-
-* default: `true`.
-* key: `short-option-groups`.
-
-Should a group of short-options be treated as boolean flags?
-
-```sh
-node example.js -abc
-{ _: [], a: true, b: true, c: true }
-```
-
-_if disabled:_
-
-```sh
-node example.js -abc
-{ _: [], abc: true }
-```
-
-### camel-case expansion
-
-* default: `true`.
-* key: `camel-case-expansion`.
-
-Should hyphenated arguments be expanded into camel-case aliases?
-
-```sh
-node example.js --foo-bar
-{ _: [], 'foo-bar': true, fooBar: true }
-```
-
-_if disabled:_
-
-```sh
-node example.js --foo-bar
-{ _: [], 'foo-bar': true }
-```
-
-### dot-notation
-
-* default: `true`
-* key: `dot-notation`

-node example.js --foo.bar
-{ _: [], foo: { bar: true } }
-```
-

-
-```sh
-node example.js --foo.bar
-{ _: [], "foo.bar": true }
-```
-
-### parse numbers
-
-* default: `true`
-* key: `parse-numbers`

-```
-
-_if disabled:_
-
-```sh
-node example.js --foo=99.3
-{ _: [], foo: "99.3" }
-```
-

-## Special Thanks
-
-The yargs project evolves from optimist and minimist. It owes its
-existence to a lot of James Halliday's hard work. Thanks [substack](https://github.com/substack) **beep** **boop** \o/
