 $! 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.
