Bugzilla 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 accessed 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], [ActiveState], OpenOffice 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]]] ---- See also [SCM].
