=head1 EXIT STATUS

Non-Zero on grave errors, otherwise zero. Note that there are cases where

B<efa> returns zero although it didn't work properly (i.e. displays an empty

result).

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

gave ambiguous input and need to re-run B<efa> with different arguments. 255

on any other kind of error.

=head1 CONFIGURATION

=head1 DEPENDENCIES

This script requires the WWW::Mechanize module and perl 5.10 (or higher).

This script requires perl 5.10 (or higher) with the modules

HTML::TreeBuilder::XPath and WWW::Mechanize.

=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

caution.
