This kind of file is also used to represent icon images of Web sites, for instance in bookmark lists. Therefore it is supported by many types of browsers, including those that run on non-Windows operating systems.

An icon file may contain several alternative versions of the same icon image in different sizes and color depths.

I used a remote icon because phpclasses wouldn't let me upload the file. It gets slow when you run the tests so please download the ico and change the test scripts or use your icons ;) There's no documentation, the classes are simple. Open the source and look to the comments.
