parse argument options

This module is the guts of optimist's argument parser without all the

fanciful decoration.

# example

``` js

var argv = require('minimist')(process.argv.slice(2));

console.dir(argv);

```

```

$ node example/parse.js -a beep -b boop

{ _: [], a: 'beep', b: 'boop' }

```

```

$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz

{ _: [ 'foo', 'bar', 'baz' ],

  x: 3,

  y: 4,

  n: 5,

  a: true,

  b: true,

  c: true,

  beep: 'boop' }

```

# methods

``` js

var parseArgs = require('minimist')

```

## var argv = parseArgs(args, opts={})

Return an argument object `argv` populated with the array arguments from `args`.

`argv._` contains all the arguments that didn't have an option associated with

them.

Numeric-looking arguments will be returned as numbers unless `opts.string` or

`opts.boolean` is set for that argument name.

Any arguments after `'--'` will not be parsed and will end up in `argv._`.

options can be:

* `opts.string` - a string or array of strings argument names to always treat as

strings

* `opts.boolean` - a boolean, string or array of strings to always treat as

booleans. if `true` will treat all double hyphenated arguments without equal signs

as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)

* `opts.alias` - an object mapping string names to strings or arrays of string

argument names to use as aliases

* `opts.default` - an object mapping string argument names to default values

* `opts.stopEarly` - when true, populate `argv._` with everything after the

first non-option

* `opts['--']` - when true, populate `argv._` with everything before the `--`

and `argv['--']` with everything after the `--`. Here's an example:

* `opts.unknown` - a function which is invoked with a command line parameter not

defined in the `opts` configuration object. If the function returns `false`, the

unknown option is not added to `argv`.

```

> require('./')('one two three -- four five --six'.split(' '), { '--': true })

{ _: [ 'one', 'two', 'three' ],

  '--': [ 'four', 'five', '--six' ] }

```

Note that with `opts['--']` set, parsing for arguments still stops after the

`--`.
