CVS commit analyser

This software review is about the CVS commit analyser, a tool that consists of three simple Perl scripts that generate weekly statistics on the CVS activity for the GNOME Project. The tool has been made available to the public as multiple people have expressed interest in using it.

The first script, countcommits.pl, receives CVS commit emails on standard input and stores the data in a specified file. The script can be used in conjunction with an Exim filter to feed the relevant data.

The second script, analysecommits.pl, performs analysis on the stored data and generates a list of the top 20 active modules and active developers. The output of this analysis can be seen in the sample output section below.

The third and final script, rotateandmail.pl, rotates the data file and sends an email containing the output of the aforementioned analysis.
