+$! This procedure compares the files in two directories and reports the
+$! 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 codde 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.
