Bugzilla is a powerful bug tracking system used by a large number of open
source projects.  

In order to use Bugzilla, you will first need to configure it for your 
environment.  The first step to doing this is to run the checksetup.pl
script, which will perform module version checks and create an initial
config file in /etc/bugzilla called localconfig.  You then need to ensure
the values in this file are accurate for your environment.

Once this is done, you may need to modify default settings for your database
to ensure it accepts Bugzilla data properly.  Please see 
http://www.bugzilla.org/docs/4.0/en/html/configuration.html for specifics of 
database setting modifications.

Lastly, simply re-run checksetup.pl to populate the database tables, set up
the templates, and add the administrator ID.  You should be done at this point.

There are two useful cron jobs which are included with Bugzilla which should be
put in place after configuration is done.  The first is a daily cron job for 
statistics collection.  This is in the file "cron.daily" and can be enabled by
simply copying this file to /etc/cron.daily/bugzilla (or any other file name
in the /etc/cron.daily/ directory).  The second is the "whine" cron job,
designed to run every 15 minutes.  To enable this job, simply copy the
cron.whine file to /etc/cron.d/bugzilla (or any othe filename within the
/etc/cron.d/ directory).
