><P
>&#13;      Bugzilla is one example of a class of programs called "Defect
Tracking Systems", or, more commonly, "Bug-Tracking Systems".  Defect
Tracking Systems allow individual or groups of developers to keep
track of outstanding bugs in their product effectively. Bugzilla was
originally written by Terry Weissman in a programming language called
"TCL", to replace a crappy bug-tracking database used internally by
Netscape Communications.  Terry later ported Bugzilla to Perl from
TCL, and in Perl it remains to this day. Most commercial
defect-tracking software vendors at the time charged enormous
licensing fees, and Bugzilla quickly became a favorite of the
open-source crowd (with its genesis in the open-source browser
project, Mozilla).  It is now the de-facto standard defect-tracking
system against which all others are measured.
