$! This procedure compares the files in two directories and reports the
$! differences.  It is customized for the vmsports repository layout.
$!
$! It needs to be customized to the local site directories.
$!
$! This is used by me for these purposes:
$!     1. Compare the original source of a project with an existing
$!        VMS port.
$!     2. Compare the checked out repository of a project with the
$!        the local working copy to make sure they are in sync.
$!     3. Keep a copy directory up to date.  The third is needed by
$!        me because VMS Backup can create a saveset of files from a
$!        NFS mounted volume.
$!
$! First the files in the original source directory which is assumed to be
$! under source code control are compared with the copy directory.
$!
$! Then the files are are only in the copy directory are listed.
$!
$! The result will five diagnostics about of files:
$!    1. Files that are not generation 1.
$!    2. Files missing in the copy directory.
$!    3. Files in the copy directory not in the source directory.
$!    4. Files different from the source directory.
$!    5. Files that VMS DIFF can not process.
$!
$! This needs to be run on an ODS-5 volume.
$!
$! If UPDATE is given as a second parameter, files missing or different in the
$! copy directory will be updated.
$!
$! By default:
$!    The directory src_root:[project_name] will be translated to something like
$!    DISK:[dir.dir.reference.project_name] and this will be used
$!    to calculate DISK:[dir.dir.vms_source.project_name] for the VMS specific
$!    source directory.
$!
$!    The copy directory is vms_root:[project_name]
$!    The UPDATE parameter is ignored.
$!
$!    This setting is used to make sure that the working vms directory
$!    and the repository checkout directory have the same contents.
$!
$! If P1 is "SRCBCK" then this
$!     The source directory tree is: src_root:[project_name]
$!     The copy directory is src_root1:[project_name]
$!
$!   src_root1:[project_name] is used by me to work around that VMS backup will
$!   not use NFS as a source directory so I need to make a copy.
$!
$!   This is to make sure that the backup save set for the unmodified
$!   source is up to date.
$!
$!   If your repository checkout is not on an NFS mounted volume, you do not
$!   need to use this option or have the logical name src_root1 defined.
$!
$! If P1 is "VMSBCK" then this changes the two directories:
$!    The source directory is vms_root:[project_name]
$!    The copy directory is vms_root1:[project_name]
$!
$!   vms_root:[project_name] is where I do the VMS specific edits.
$!   vms_root1:[project_name] is used by me to work around that VMS backup will
$!   not use NFS as a source directory so I need to make a copy.
$!
$!   This is to make sure that the backup save set for the unmodified
$!   source is up to date.
