=head1 NAME
Bugzilla::Keyword - A Keyword that can be added to a bug.
=head1 SYNOPSIS
use Bugzilla::Keyword;
my $description = $keyword->description;
my $keywords = Bugzilla::Keyword->get_all_with_bug_count();
=head1 DESCRIPTION
Bugzilla::Keyword represents a keyword that can be added to a bug.
This implements all standard C<Bugzilla::Object> methods. See
L<Bugzilla::Object> for more details.
=head1 SUBROUTINES
This is only a list of subroutines specific to C<Bugzilla::Keyword>.
See L<Bugzilla::Object> for more subroutines that this object
implements.
=over
=item C<get_all_with_bug_count()>
Description: Returns all defined keywords. This is an efficient way
to get the associated bug counts, as only one SQL query
is executed with this method, instead of one per keyword
when calling get_all and then bug_count.
Params: none
Returns: A reference to an array of Keyword objects, or an empty
arrayref if there are no keywords.
