Diff Utils library is an OpenSource library for performing the comparison operations between texts: computing diffs, applying patches, generating unified diffs or parsing them, generating diff output for easy future displaying (like side-by-side view) and so on.

Main reason to build this library was the lack of easy-to-use libraries with all the usual stuff you need while working with diff files. Originally it was inspired by JRCS library and it's nice design of diff module.

* computing the difference between two texts.

* capable to hand more than plain ascii. Arrays or List of any type that implements hashCode() and equals() correctly can be subject to differencing using this library

But it can easily replaced by any other which is better for handing your texts. I have plan to add implementation of some in future.
