Have you ever need to lookup something in source code? Most developers probably did so. I needed to lookup something in Gammu sources and I decided to setup search engine over it. I decided to use Gonzui as it looks good and was easy to setup. So if you want to find something in sources, just point your browser to gonzui.cihar.com.
Later I added also other my code (phpMyAdmin, Wammu, python-gammu, polld), so you probably want to use advanced search to limit results.
