$! Procedure to create backup save sets for installing in a PCSI kit.
$!
$! To comply with most Open Source licenses, the source used for building
$! a kit will be packaged with the distribution kit for the binary.
$!
$! Backup save sets are the only storage format that I can expect a
$! VMS system to be able to extract ODS-5 filenames and directories.
$!
$! The make_pcsi_kit_name.com needs to be run before this procedure to
$! properly name the files that will be created.
$!
$! This file is created from a template file for the purpose of making it
$! easier to port Unix code, particularly open source code to VMS.
$! Therefore permission is freely granted for any use.
