$! 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.
