Rewrite code examples in Markdown code blocks as test assertions.

Turns this:

# Title of Your README.md

This is _Markdown_!

<!--javascript
  var additionModule = require('./');
-->

The above won't be rendered in HTML, such as on GitHub or
npmjs.com, but it will be included in the rewritten
JavaScript.

The JavaScript expressions with comments that follow will
be rewritten as asssertions.

```javascript
additionmodule(1, 1); // => 2
additionmodule(2, 2); // => 4
```

into this:

var additionModule = require('./');
__jsmd__(additionModule(l, 1), 2, 'line 1');
__jsmd__(additionModule(2, 2), 4, 'line 2');

Command-Line Interface

$ npm install --global jsmd-rewrite
$ jsmd-rewrite --version
$ jsmd-rewrite --help
$ jsmd-rewrite README.md
$ cat README.md | jsmd-rewrite

Node.js

Install:

$ npm install --save jsmd-rewrite

then:

var rewrite = require('jsmd-rewrite');
rewrite(markdown); // returns string
rewrite(markdown, assertionFunctionName); // returns string

The function name used for assertions is "__jsmd__" by default.
