=head1 DESCRIPTION

Determines the medium used to run the Perl Script and implements the resources
to handle the user input and process output.  Simplifies the interaction
mechanism and enables the Perl Script to be used in different mediums.  See
L<Anansi::ComponentManager> for inherited methods.

=head1 METHODS

=cut


=head2 channelComponent

    my $return = $OBJECT->channelComponent($component, 'some channel');

Attempts to create a new subroutine to enable the direct use of a channel of the
currently loaded component and define it as a channel of this module.  If a
channel with the same name as the component channel already is defined for this
module then it silently fails.  If a subroutine with the same name as the
channel does not exist in this module's namespace then that subroutine name is
used otherwise it remains anonymous.  Returns B<0> I<(zero)> on failure and B<1>
I<(one)> on success.
