From 66ca50e198ed2989b97293fac59de30f1be48bd3 Mon Sep 17 00:00:00 2001

Subject: Rework dahdi_genconf to have separate configuration generation
 modules.

'dahdi_genconf foo bar' will use the modules Dahdi::Config::Gen::Foo and
Dahdi::Config::Gen::Bar to generate configuraion files. Extra formats
can thus be added without modifying dahdi_genconf and independently of
DAHDI.

-dahdi_genconf [FILES...]
+dahdi_genconf [options] [generator...]
 
 =head1 DESCRIPTION
 
-This script generate configuration files for DAHDI hardware. The
-parameters are types of files to generate. By default it will generate
-the types 'dahdi' and 'chan_dahdi'. See below a complete list.
+This script generate configuration files for Dahdi hardware.
+It uses two information sources:
 
 =over 4
 
-=item dahdi - /etc/dahdi/system.conf
-
-Configuration for dahdi_cfg(1). Its location may be overriden by the
-environment variable DAHDI_CONF_FILE.
-
-=item modules /etc/dahdi/modules
-
-List of DAHDI kernel modules to be loaded by the init.d script. One
-module per line. Its location may be overriden with the variable
-DAHDI_MODS_FILE.
+=item Hardware
 
-=item chan_dahdi - /etc/asterisk/dahdi-channels.conf
+ The actual dahdi hardware is automatically detected on the host.
 
-Configuration for asterisk(1). It should be included in the main /etc/asterisk/chan_dahdi.conf.
-Its location may be overriden by the environment variable 
-CHAN_DAHDI_CHANNELS_FILE.
+=item /etc/dahdi/genconf_params
 
-=item users - /etc/asterisk/users.conf
+A configuration file that supplements the hardware information.
+Its location may be overriden via the C<GENCONF_PARAMETERS> environment
+variable.
 
-Configuration for asterisk(1) and AsteriskGUI.
-Its location may be overriden by the environment variable USERS_FILE.
-
-=item asterisk - /var/lib/asterisk/asterisk-detected-zap.conf
-
-Dump information (hardware, spans and channels) in the format of an 
-Asterisk configuration file.
+=back
 
-=item chan_dahdi_full - /etc/asterisk/chan_dahdi.conf
+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.
 
-Configuration for asterisk(1) and AsteriskGUI.
-Its location may be overriden by the environment variable CHAN_DAHDI_CONF_FILE.
+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>
 
-=back
+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:
 
-=head1 EXAMPLES
+ dahdi_genconf system chandahdi=verbose unicall
 
-Generate /etc/dahdi/system.conf ('dahdi') and a snippet of
-chan_dahdi.conf ('chan_dahdi'):
+Global options:
 
-  dahdi_genconf
-
-Create those two files, and /etc/dahdi/modules:
+=over 4
 
-  dahdi_genconf chan_dahdi dahdi modules
+=item -v
 
-Print Asterisk configuration-file formatted report to the standard
-output:
+Verbose -- also sets the C<'verbose'> option for all generators.
