kdesvn kompare diff script

Linux
Perl

This is just a simple perl script that makes it easy to do svn diffs in kompare. Basically, just put it in your bin dir and then from your svn working dir you can just say svndiffr filename or svndiffr path/filename. The script will print out the svn log for the file and ask you for a revision. Enter the revision number you want to diff you working copy with and hit enter. Kompare will launch with the revision on the left and the working copy on the right so that changes are saved to the working copy.
