=head1 NAME
zapata - Generate configuration for zapata channels.
=head1 SYNOPSIS
use Zaptel::Config::Gen::Zapata;
my $cfg = new Zaptel::Config::Gen::Zapata(\%global_config, \%genopts);
$cfg->generate(@span_list);
=head1 DESCRIPTION
Generate the F</etc/asterisk/zapata-channels.conf>
This is used as a configuration for asterisk(1).
It should be included in the main F</etc/asterisk/zapata.conf>.
Its location may be overriden via the environment variable
C<ZAPATA_FILE>.
=head1 OPTIONS
=over 4
=item freepbx
With this option we do not generate channel definitions for FXS, Input and
Output ports. This is done because these channel definitions need to be
generated and inserted into I<freepbx> database anyway.
=back
The I<freepbx> option may be activated also by adding a C<freepbx yes> line
to the C<genconf_parameters> file.
