1.13      harris41  102: Standard input provides the list of files to work with.
                    103: TAG, required descriptive tag.  For example, a kerberos software
1.16      harris41  104: package might be tagged as "krb4". (This value is also used in
                    105: the generation of a temporary directory; you cannot have
                    106: a pre-existing directory named ./TAG.)
1.13      harris41  107: VERSION, required version.  Needed to generate version information
1.16      harris41  108: for the RPM.  It is recommended that this be in the format N.M where N and
                    109: M are integers.

                    114: treated as documentation files by RPM (and thus subject to being

                    116: PATHPREFIX, optional path to be removed from file listing.  This
                    117: is in case you are building an RPM from files elsewhere than

1.16      harris41  122: description, and pre-installation scripts (see more in the POD,

1.13      harris41  665: 
1.16      harris41  666: B<make_rpm.pl> generates and then deletes temporary
1.15      harris41  667: files needed to build an RPM with.
                    668: It works cleanly and independently from pre-existing

1.13      harris41  670: 
1.16      harris41  671: Input to the script is simple.  B<make_rpm.pl> accepts five kinds of
