+Description
+===========
+
+streamsearch is a module for [node.js](http://nodejs.org/) that allows searching a stream using the Boyer-Moore-Horspool algorithm.
+
+This module is based heavily on the Streaming Boyer-Moore-Horspool C++ implementation by Hongli Lai [here](https://github.com/FooBarWidget/boyer-moore-horspool).
+
+
+Requirements
+============
+
+* [node.js](http://nodejs.org/) -- v0.8.0 or newer
+
+
+Installation
+============
+
+    npm install streamsearch
+
+Example
+=======
+
+```javascript
+  var StreamSearch = require('streamsearch'),
+      inspect = require('util').inspect;
+
+  var needle = new Buffer([13, 10]), // CRLF
+      s = new StreamSearch(needle),
+      chunks = [
+        new Buffer('foo'),
+        new Buffer(' bar'),
+        new Buffer('\r'),
+        new Buffer('\n'),
+        new Buffer('baz, hello\r'),
+        new Buffer('\n world.'),
+        new Buffer('\r\n Node.JS rules!!\r\n\r\n')
+      ];
+  s.on('info', function(isMatch, data, start, end) {
+    if (data)
+      console.log('data: ' + inspect(data.toString('ascii', start, end)));
+    if (isMatch)
+      console.log('match!');
+  });
+  for (var i = 0, len = chunks.length; i < len; ++i)
+    s.push(chunks[i]);
+
+  // output:
+  //
+  // data: 'foo'
+  // data: ' bar'
+  // match!
+  // data: 'baz, hello'
+  // match!
+  // data: ' world.'
+  // match!
+  // data: ' Node.JS rules!!'
+  // match!
+  // data: ''
+  // match!
+```
+
+
+API
+===
+
+Events
+------
+
+* **info**(< _boolean_ >isMatch[, < _Buffer_ >chunk, < _integer_ >start, < _integer_ >end]) - A match _may_ or _may not_ have been made. In either case, a preceding `chunk` of data _may_ be available that did not match the needle. Data (if available) is in `chunk` between `start` (inclusive) and `end` (exclusive).
+
+
+Properties
+----------
+
+* **maxMatches** - < _integer_ > - The maximum number of matches. Defaults to Infinity.
+
+* **matches** - < _integer_ > - The current match count.
+
+
+Functions
+---------
+
+* **(constructor)**(< _mixed_ >needle) - Creates and returns a new instance for searching for a _Buffer_ or _string_ `needle`.
+
+* **push**(< _Buffer_ >chunk) - _integer_ - Processes `chunk`. The return value is the last processed index in `chunk` + 1.
+
+* **reset**() - _(void)_ - Resets internal state. Useful for when you wish to start searching a new/different stream for example.
