This is +deprecated; if gendistrib finds a F<media.cfg> file, it will use it and ignore +the F<hdlists> file unless this option is given. + +=item --mediacfg file + +Use the specified F<media.cfg> file (defaults to F<media/media_info/media.cfg>). + +=item --nobadrpm + +Don't abort when encountering bad rpms. + +=item --noemptymedia + +Stop and abort if an empty media is found. + +=item --nomd5sum + +Don't generate MD5SUM files. + +=item --skipmissingdir + +If a media dir is missing, ignore it instead of aborting. + +=item -s + +Silent mode. + +=back + +=head1 DESCRIPTION + +F<gendistrib> is a tool that helps to generate the structure of a Mandriva +RPM repository, compatible with Mandriva tools (F<urpmi>, F<rpmdrake>, +etc.) + +=head2 General Structure of a Repository + +A typical repository, under a root directory F</ROOT/>, has the following +structure: + + ROOT/ - media/ + |- contrib/ + | `- media_info/ + |- main/ + | `- media_info/ + `- media_info/ + +In this example, we have two media, called I<main> and I<contrib>. The +RPMs packages are placed in the F<main> and F<contrib> subdirectories. +Repository metadata is contained in the top-level F<media_info> directory. +Per-media metadata are contained in the F<main/media_info> and +F<contrib/media_info> subdirectories. + +=head2 Configuration of the distribution tree + +Before using F<gendistrib>, you must create a file F<media_info/media.cfg> +to describe your repository. (An empty file will work, but this isn't +recommended.) The syntax of this file is reminiscent of F<.ini> files. + +A first section C<[media_info]> contains global information about the +repository: + + [media_info] + version=2006.0 + branch=Cooker + arch=i586 + +Then, supply one section per media. + + [main] + hdlist=hdlist_main.cz + name=Main + +Here, the C<hdlist> parameter specifies what will be the name of the +hdlist file in the top-level F<media_info> directory. C<name> is a human +readable label for the media. + +=head2 Operation + +F<gendistrib> should be passed the F<ROOT> directory as parameter. It will +then generate the hdlist and synthesis files and all other files needed +for proper repository operation. + +=head1 SEE ALSO + +genhdlist2(1), and MDV::Distribconf(3) for description of the format of the +F<media.cfg> file. + +=head1 COPYRIGHT + +Copyright (C) 1999, 2000, 2001, 2002, 2003, 2004, 2005 MandrakeSoft SA + +Copyright (C) 2005, 2006 Mandriva SA + +This program is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 2, or (at your option) +any later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
