DirDiff

Comparing two different versions of a directory with text files of any kind has never been easier.
Detects deleted files, new files, files with changed name but same content and of course a side-by-side / line-by-line comparison of changed files. Number of context-lines is configurable. Here's, how to call it:

>python DirDiff.py dir1 dir2 output.html
or
>python.exe DirDiff.py -l 3 -v olddir newdir dirdiff.html

-l is the number of context lines in the side-by-side comparison.
-v lists all files, that exist in both directories and have the same content.

Both directory names need to end with the "/" (Linux) or "\" (Windows).
