=head1 NAME
dahdi_genconf - Generate configuration for dahdi channels.
=head1 SYNOPSIS
dahdi_genconf [options] [generator...]
=head1 DESCRIPTION
This script generate configuration files for Dahdi hardware.
It uses two information sources:
=over 4
=item Hardware
The actual dahdi hardware is automatically detected on the host.
=item /etc/dahdi/genconf_parameters
A configuration file that supplements the hardware information.
Its location may be overriden via the C<GENCONF_PARAMETERS> environment
variable.
=back
The dahdi_genconf script can generate various kinds of configuration files
as specificed by the generator arguments. Each generator is a perl classes
in Dahdi::Config::Gen namespace. The generator names on the command line
are the class names in lowercase.
The following generators are currently implemented: system, chandahdi, unicall, users.
For further documentation on each, please user perldoc on the relevant
class. E.g: C<perldoc Dahdi::Config::Gen::Chandahdi>
Each generator on the command line may be passed custom options by assigning
a comma separated list of options to the generator name. E.g:
dahdi_genconf system chandahdi=verbose unicall
=head2 Global options:
=over 4
=item -V
Version -- print version string and exit.
=item -v
Verbose -- sets the C<'verbose'> option for all generators.
=item -F
Freepbx -- sets the C<'freepbx'> option for all generators.
Currently, chandahdi is affected.
=back
=head2 Implementation notes:
=over 4
=item *
F<genconf_parameters> parsing is done via C<Dahdi::Config::Params>.
An object representing the parsed data is instanciated by:
C<Dahdi::Config::Params-E<gt>new()>.
The C<item()> method of this object contains all the hard coded
defaults of the configuration directives.
=item *
A configuration object is instanciated by C<Dahdi::Config::Gen-E<gt>new($params)>.
The mapping of configuration directives into semantic configuration is
done in the constructor.
=item *
A single generator is run via the the C<run_generator()> method of the
configuration object.
