=head1 NAME

tv_validate_grabber - Validate that an xmltv grabber works correctly

=head1 SYNOPSIS

tv_validate_grabber --help

tv_validate_grabber [--config-file <configfile>] [--keep-files] <cmd>

=head1 DESCRIPTION

tv_validate_grabber runs a grabber through a series of test to determine
if it follows the recommendations described at 
L<http://wiki.xmltv.org/index.php/XmltvCapabilities>

tv_validate_grabber does not assume that the grabber is written in perl.
The command does not have to be a single executable, it can also be a complete
command-line:

tv_validate_grabber "perl -I lib grab/new/tv_grab_new"

=head1 OPTIONS

B<--config-file <configfile>> Use the specified file as configuration file
for the grabber. If the file does not exist,
the grabber is run with --configure to 
create it. Default is to always run the grabber
with --configure first and store the configuration
in a temporary file.

B<--keep-files> Do not delete the output-files generated during
the validation.
