5$! This procedure compares the files in two directories and reports the
6$! differences.  It is customized for the vmsports repository layout.
7$!
8$! It needs to be customized to the local site directories.
9$!
10$! This is used by me for these purposes:
11$!     1. Compare the original source of a project with an existing
12$!        VMS port.
13$!     2. Compare the checked out repository of a project with the
14$!        the local working copy to make sure they are in sync.
15$!     3. Keep a copy directory up to date.  The third is needed by
16$!        me because VMS Backup can create a saveset of files from a
17$!        NFS mounted volume.
18$!
19$! First the files in the original source directory which is assumed to be
20$! under source codde control are compared with the copy directory.
21$!
22$! Then the files are are only in the copy directory are listed.
23$!
24$! The result will five diagnostics about of files:
25$!    1. Files that are not generation 1.
26$!    2. Files missing in the copy directory.
27$!    3. Files in the copy directory not in the source directory.
28$!    4. Files different from the source directory.
29$!    5. Files that VMS DIFF can not process.
30$!
31$! This needs to be run on an ODS-5 volume.
32$!
33$! If UPDATE is given as a second parameter, files missing or different in the
34$! copy directory will be updated.
35$!
36$! By default:
37$!    The directory src_root:[project_name] will be translated to something like
38$!    DISK:[dir.dir.reference.project_name] and this will be used
39$!    to calculate DISK:[dir.dir.vms_source.project_name] for the VMS specific
40$!    source directory.
41$!
42$!    The copy directory is vms_root:[project_name]
43$!    The UPDATE parameter is ignored.
44$!
45$!    This setting is used to make sure that the working vms directory
46$!    and the repository checkout directory have the same contents.
47$!
48$! If P1 is "SRCBCK" then this
49$!     The source directory tree is: src_root:[project_name]
50$!     The copy directory is src_root1:[project_name]
51$!
52$!   src_root1:[project_name] is used by me to work around that VMS backup will
53$!   not use NFS as a source directory so I need to make a copy.
54$!
55$!   This is to make sure that the backup save set for the unmodified
56$!   source is up to date.
57$!
58$!   If your repository checkout is not on an NFS mounted volume, you do not
59$!   need to use this option or have the logical name src_root1 defined.
60$!
61$! If P1 is "VMSBCK" then this changes the two directories:
62$!    The source directory is vms_root:[project_name]
63$!    The copy directory is vms_root1:[project_name]
64$!
65$!   vms_root:[project_name] is where I do the VMS specific edits.
66$!   vms_root1:[project_name] is used by me to work around that VMS backup will
67$!   not use NFS as a source directory so I need to make a copy.
68$!
69$!   This is to make sure that the backup save set for the unmodified
70$!   source is up to date.
