+Zero if everything went well (or at least if B<efa> thinks so), one if you

=head1 BUGS AND LIMITATIONS
-The Unicode handling is slightly messed up. Therefore, arguments to B<efa>
-should always be plain ASCII (ue instead of E<uuml> etc).
+B<efa> cannot handle Unicode in its arguments, so use plain ASCII.

+The Parser is quite new and may not yet cover all corner cases, use with
