+ +=head1 DESCRIPTION + +Automatically generate an RPM software package from a list of files. + +B builds the RPM in a very clean and configurable fashion. +(Finally! Making RPMs outside of F without a zillion +file intermediates left over!) + +B generates and then deletes temporary +files needed to build an RPM with. +It works cleanly and independently from pre-existing +directory trees such as F. + +Input to the script is simple. B accepts five kinds of +information, three of which are mandatory: + +=over 4 + +=item * + +(required) a list of files that are to be part of the software package; + +=item * + +(required) the absolute filesystem location of these files +(see L<"The standard input stream">); + +=item * + +(required) a descriptive tag and a version tag for the naming of the +RPM software package; + +=item * + +(optional) documentation and configuration files; + +=item * + +and (optional) an XML file that defines the additional metadata +associated with the RPM software package. + +=back + +A temporary directory named $tag (first argument described in +L<"Description of command-line arguments">) is + +=over 4 + +=item * + +generated under the directory from which you run B. + +For example, user "joe" running + + cat file_list.txt | make_rpm.pl krb4 1.0 + +would temporarily generate F. + +=item * + +F is deleted after the *.rpm +file is generated. + +=back + +The RPM will typically be named $name-$version.i386.rpm +where $name=$tag. (The $name can be overridden in the customization +XML file; see +L<"Customizing descriptive data of your RPM software package">.) + +Here are some of the items are generated inside +the $tag directory during the construction of an RPM: + +=over 4 + +=item * + +RPM .spec file (F<./$tag/SPECS/$name-$version.spec>) + +=item * + +RPM Makefile (F<./$tag/SOURCES/$name-$version/Makefile>) + +This is the Makefile that is called by the rpm +command in building the .i386.rpm from the .src.rpm. +The following directories are generated and/or used: + +=over 4 + +=item * + +SOURCE directory: F<./$tag/BinaryRoot/> + +=item * + +TARGET directory: F<./$tag/BuildRoot/> + +=back + +=item * + +BinaryRootMakefile (F<./$tag/BinaryRootMakefile>) + +This is the Makefile that this script creates and calls +to build the F<$tag/BinaryRoot/> directory from the existing +filesystem. +The following directories are generated and/or used: + +=over 4 + +=item * + +SOURCE directory: / (your entire filesystem) + +=item * + +TARGET directory: F<./$tag/BinaryRoot/> + +=back + +=back + +The final output of B is a binary F<.rpm> file. +The F<./tag> directory is deleted (along with the F<.src.rpm> +file). The typical file name generated by B is +F<$tag-$version.i386.rpm>. + +B is compatible with either rpm version 3.* or rpm version 4.*. + +=head1 README + +Automatically generate an RPM software package from a list of files. + +B builds the RPM in a very clean and configurable fashion. +(Making RPMs "the simple way" in a one-line command.) + +B generates and then deletes temporary +files (and binary root directory tree) to build an RPM with. +It is designed to work cleanly and independently from pre-existing +directory trees such as /usr/src/redhat/*. + +=head1 PREREQUISITES + +This script requires the C module. + +=head1 AUTHOR + + Scott Harrison + harris41@msu.edu + +Please let me know how/if you are finding this script useful and +any/all suggestions. -Scott + +=head1 LICENSE + +Written by Scott Harrison, harris41@msu.edu + +Copyright Michigan State University Board of Trustees + +This file is part of the LearningOnline Network with CAPA (LON-CAPA). + +This 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 of the License, or +(at your option) any later version. + +This file 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.
