googlediff v0.1.0
node module for: http://code.google.com/p/google-diff-match-patch/ by Neil Fraser and contributors.
drop in the original code form svn of Neil Fraser's diff_match_patch. uses jsinc and a simple index.js file and thus it is easily updatable
to update just copy in here the 'demos' and 'javascript' folders
this module is also awesome because you can use exactrly the same code on the serverside and on the client side.
this module is built using https://github.com/shimondoodkin/jsinc
the test tests just that the modue is usable.
see demos to learn how it works.
