XMLTV::PreferredMethod(3) Adds a preferredmethod argument to XMLTV grabbers


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.
