Finally, I have achieved to push my first git repository at github.com. This repo is a set formed by silly (but usefull) tools: awstats-update.
Basically, this tools are a couple de scripts which can be executed as cronjobs. These, periodically, are checking if exist new sites enabled in the apache/nginx configuration and building the corresponding awstats configuration file for them.
The repository can be accessed from:
git://github.com/psaavedra/awstats-update.git
