XMLTV::PreferredMethod - Adds a preferredmethod argument to XMLTV grabbers
=head1 DESCRIPTION
Add a --preferredmethod argument to your program, eg
use XMLTV::PreferredMethod 'allatonce';
If a --preferredmethod parameter is supplied on the command-line, it will
be caught already by the "use" statement, the string supplied in the use-line
will be printed to STDOUT and the program will exit.
Don't forget to announce the preferredmethod capability as well.
