## API

### parseArgs(opts, [minimistOptions])

Returns an Object with:

- input (Array) - Non-flag arguments
- flags (Object) - Flags converted to camelCase
- help (string) - The help text used with --help
- showHelp([code=0]) (Function) - Show the help text and exit with code

#### options

Type: `Object` `Array` `string`

Can either be a string/array that is the `help` or an options object.

##### help

Type: `string` `boolean`
The help text you want shown.

Set it to `false` to disable it altogether.

##### version

Type: `string` `boolean`
Default: `electron.app.getVersion()`

Set a custom version output.

Set it to false to disable it altogether.

##### argv

Type: `Array`

Custom arguments object.


#### minimistOptions

Type: `Object`
Default: `{}`

Minimist options.

Keys passed to the minimist default option are decamelized, so you can for example pass in fooBar: 'baz' and have it be the default for the --foo-bar flag.
