cli-usage

Easily show the usage of your CLI tool from a Markdown string
or file. You can just plug cli-usage in without thinking
about paramters, or you can handle that your self using the
.get API end-point.

Install

``
npm install cli-usage
`

Usage

Most basic usage, just plug in:

`javascript
var usage = require('cli-usage');
usage();
//=> If help-flag is passed, print usage
//=> and exit with code 0.
`

This will listen for -h, -help or --help passed
into your CLI and try to locate a usage.md file from
the directory of the file. If help is passed and the
usage.md file found, the usage will be printed and
the application will exit with code 0.

You can also pass in a filename or a string.

`javascript
var usage = require('cli-usage');
usage('./some/path/to/usage.md');
`

or

`javascript
var usage = require('cli-usage');
usage('# Simple usage');
`

Instead of cli-usage doing all the work, you can
also just retrieve the compiled usage text and handle
it your self.

#### Example
`javascript
var usage = require('cli-usage');

console.log(usage.get('# some custom markdown from string'));

console.log(usage.get('./usage.md'));
