Bugzilla [L1 ] is a bug tracking system that was constructed to handle issues raised against the Mozilla project. Originally written in Tcl it was ported to Perl by Netscape engineers. Bugzilla uses a MySQL database to hold the bug data and is accesed through CGI scripts written in Perl. Bugzilla is rapidly becoming the most widely used bug tracking system for open source projects. Notable installations include RedHat [L2 ], ActiveState [L3 ], OpenOffice [L4 ] and of course the Mozilla project. The most recent versions of bugzilla provide a templating mechanism to permit sites to customize the HTML output without having to hack the perl source quite so much. [PT]
