Hello,

Anyone knows of any tool that can generate a diff between two files
and output HTML code that i could use in a page?

Doesn't need to be a Ruby tool, any Unix compatible tool would do the
trick, I just need it to output HTML.

I was looking for something that could turn the diff output into nice
HTML, but thanks anyway.
