XMLTV::Version - Adds a --version argument to XMLTV grabbers
=head1 DESCRIPTION
Add a --version argument to your program, eg
use XMLTV::Version '$Id: Version.pm,v 1.3 2010/04/24 12:28:22 crispygoth Exp $';
If a --version parameter is supplied on the command-line, it will
be caught already by the "use" statement, a message will be printed
to STDOUT and the program will exit.
It is best to put the use XMLTV::Version statement before other module
imports, so that even if they fail --version will still work.
