=head1 NAME
Bugzilla::Flag - A module to deal with Bugzilla flag values.
=head1 SYNOPSIS
Flag.pm provides an interface to flags as stored in Bugzilla.
See below for more information.

=item *
Import relevant functions from that script.
=item *
Use of private functions / variables outside this module may lead to
unexpected results after an upgrade. Please avoid using private
functions in other files/modules. Private functions are functions
