+Shellwords provides functions to manipulate strings according to the word parsing rules of the UNIX Bourne shell. It is based on [the Ruby module of the same name](http://www.ruby-doc.org/stdlib-1.9.3/libdoc/shellwords/rdoc/Shellwords.html).
+
+## Installation
+
+Add "shellwords" to your `package.json` file and run `npm install`.
+
+## Example
+
+``` javascript
+var shellwords = require("shellwords");
+
+shellwords.split("foo 'bar baz'");
+// ["foo", "bar baz"]
+
+shellwords.escape("What's up, yo?");
+// 'What\\\'s\\ up,\\ yo\\?'
+```
