=head1 FUNCTIONS
+=head2 news_channels
+
+ ($count, @channels) = &news_channels($channel_name, $id_category, $unclassified);
+
+Looks up news channels by name or category.
+
+C<$channel_name> is the channel name to search.
+
+C<$id_category> is the channel category code to search.
+
+C<$$unclassified> if it is set and $channel_name and $id_category search for the news channels without a category
+
+if none of the params are set C<&news_channels> returns all the news channels.
+
+C<&news_channels> returns two values: an integer giving the number of
+news channels found and a reference to an array
+of references to hash, which has the news_channels and news_channels_categories fields.

+
+The number of news channels in that category
+
+=item C<channels>
+
+A reference to an array of references to hash which keys are the new_channels fields.
