#
# Hey, what's this?
#
# 'checksetup.pl' is a script that is supposed to run during installation
# time and also after every upgrade.
#
# The goal of this script is to make the installation even more easy.
# It does so by doing things for you as well as testing for problems
# early.
#
# And you can re-run it whenever you want. Especially after Bugzilla
# get's updated you SHOULD rerun it. Because then it may update your
# SQL table definitions so that they are again in sync with the code.
#
# So, currently this module does:
#
#     - check for required perl modules
#     - set defaults for local configuration variables
#     - create and populate the data directory after installation
#     - set the proper rights for the *.cgi, *.html ... etc files
#     - check if the code can access MySQL
#     - creates the database 'bugs' if the database does not exist
#     - creates the tables inside the database if they don't exist
#     - automatically changes the table definitions of older BugZilla
#       installations
#     - populates the groups
#     - put the first user into all groups so that the system can
#       be administrated
#     - changes already existing SQL tables if you change your local
#       settings, e.g. when you add a new platform
#
# People that install this module locally are not supposed to modify
# this script. This is done by shifting the user settable stuff intp
# a local configuration file 'localconfig'. When this file get's
# changed and 'checkconfig.pl' will be re-run, then the user changes
# will be reflected back into the database.
#
# Developers however have to modify this file at various places. To
# make this easier, I have added some special comments that one can
# search for.
#
#     To                                               Search for
#
#     add/delete local configuration variables         --LOCAL--
#     check for more prerequired modules               --MODULES--
#     change the defaults for local configuration vars --LOCAL--
#     update the assigned file permissions             --CHMOD--
#     add more MySQL-related checks                    --MYSQL--
#     change table definitions                         --TABLE--
#     add more groups                                  --GROUPS--
#
# Note: sometimes those special comments occur more then once. For
# example, --LOCAL-- is at least 3 times in this code!  --TABLE--
# also is used more than once. So search for every occurence!

# Check and update local configuration
###########################################################################

#
# This is quite tricky. But fun!
#
# First we read the file 'localconfig'. Then we check if the variables we
# need are defined. If not, localconfig will be amended by the new settings
# and the user informed to check this. The program then stops.
#
# Why do it this way around?
#
# Assume we will enhance Bugzilla and eventually more local configuration
# stuff arises on the horizon.
#
# But the file 'localconfig' is not in the Bugzilla CVS or tarfile. You
# know, we never want to overwrite your own version of 'localconfig', so
# we can't put it into the CVS/tarfile, can we?
#
# Now, we need a new variable. We simply add the necessary stuff to checksetup.
# The user get's the new version of Bugzilla from the CVS, runs checksetup
# and checksetup finds out "Oh, there is something new". Then it adds some
# default value to the user's local setup and informs the user to check that
# to see if that is what the user wants.
