+=head1 NAME
+
+Bugzilla::FlagType - A module to deal with Bugzilla flag types.
+
+=head1 SYNOPSIS
+
+FlagType.pm provides an interface to flag types as stored in Bugzilla.
+See below for more information.
+
+=head1 NOTES
+
+=over
+
+=item *
+
+Prior to calling routines in this module, it's assumed that you have
+already done a C<require CGI.pl>.  This will eventually change in a
+future version when CGI.pl is removed.
+
+=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
+whose names start with _ or are specifically noted as being private.
