+=head1 NAME
+
+make_rpm.pl - automatically generate an RPM software package
+
+=head1 SYNOPSIS
+
+Usage: <TAG> <VERSION> [CONFIGURATION_FILES]
+ [DOCUMENTATION_FILES] [PATHPREFIX] [CUSTOMIZATION_XML]
+
+Standard input provides the list of files to work with.
+
+TAG, required descriptive tag.  For example, a kerberos software
+package might be tagged as "krb4".
+
+VERSION, required version.  Needed to generate version information
+for the RPM.  This should be in the format N.M where N and M are
+integers.
+
+CONFIGURATION_FILES, optional comma-separated listing of files to
+be treated as configuration files by RPM (and thus subject to saving
+during RPM upgrades).
+
+DOCUMENTATION_FILES, optional comma-separated listing of files to be
+treated as documentation files by RPM (and thus subject to being
+placed in the /usr/doc/RPM-NAME directory during RPM installation).
+
+PATHPREFIX, optional path to be removed from file listing.  This
+is in case you are building an RPM from files elsewhere than
+root-level.  Note, this still depends on a root directory hierarchy
+after PATHPREFIX.
+
+CUSTOMIZATION_XML, allows for customizing various pieces of information such
+as vendor, summary, name, copyright, group, autoreqprov, requires, prereq,
+description, and pre-installation scripts (see more in the POD;
+perldoc make_rpml.pl).
+
+Examples:
+
+[prompt] find notreallyrootdir | perl make_rpm.pl makemoney 3.1 '' \
+    '/usr/doc/man/man3/makemoney.3' notreallyrootdir
+ would generate makemoney-3.1-1.i386.rpm
+
+[prompt] find /usr/local/bin | perl make_rpm.pl mybinfiles 1.0
+ would generate mybinfiles-1.0-1.i386.rpm
+
+[prompt] find romeo | perl make_rpm.pl romeo 1.0 '' '' '' customize.xml
+ would generate romeo with customizations from customize.xml.
+
+The CUSTOMIZATION_XML argument represents a way to customize the
+numerous variables associated with RPMs.  This argument represents
+a file name.  (Parsing is done in an unsophisticated fashion using
+regular expressions.)  Here are example contents of such a file:

+ Science and Mathematics Education, Michigan State University.

+=head1 DESCRIPTION
+
+Automatically generate an RPM software package from a list of files.
+
+This script builds the RPM in a very clean and configurable fashion.
+(Finally!  Making RPMs the simple way!)
+
+This script 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/*.
+
+Take in a file list (from standard input), 
+a description tag and version tag from command line argument
+and temporarily generate a:
+     RPM .spec file
+     RPM Makefile
+     SourceRoot
+
+A resulting .rpm file is generated.
