Mail from PARC-MAXC rcvd at 30-MAR-75 1108-EDT
Date: 30 MAR 1975 0805-PDT
From: MASINTER at PARC-MAXC
Subject: SYSCHK
To:   lewis at BBNB
cc:   TEITELMAN

OK, I have tested it out, and it works fine. The program is
<MASINTER>SYSCHK.SAV, source <MASINTER>SYSCHK.BCP (it is in BCPL).

When you start it, it asks:

"Makesys: "  respond with the name of the makesys you want to check
(e.g. <SUBSYS>LISP.SAV)

Then it asks "Send message to owners? " respond either Y or N.

If you say Yes, it will ask you for the name of an "initial message
file". This should be a text file which you create with TECO or POET
which contains the main body of the message you want sent out. Each
message will have appended to it (1) the name of the makesys, followed
by a line with "-------------" followed by a list of all of their
sysout's.

If you say No, it will ask you for the name of a file where you want
the names of the sysout's listed. You can of course say TTY: to get
them typed on the terminal.

Finally, it asks for the name of the "users" file. This file should
contain, one per line, either a single username, or 
USERNAME:dir,dir,dir,....   The initial username is the person to
whom the message is sent (his directory is not automatically checked,
you must say TEITELMAN:TEITELMAN,NEWLISP if you want to check it as
well).

Optionally the file can contain just "yourname:*" to check the
entire system.
-------------------

Notes: 
 (1) people might have files that are read protected from you.
  The program cannot see these if you are not enabled.

 (2) If a file has the same makesysdate, but it contains the name
  of a different parent (e.g. <SUBSYS>NEWLISP and <SPAGHETTI>TEST are
  identical at PARC) then it does NOT include the file name in
  any message it sends out, but DOES print the name on the terminal.
  However, if you are not sending messages, it does include the name
  in the listfile.

  (3) Sending a message to other network sites is not yet implemented,
      but will be shortly. To do this, you will be able to just
      put  HARTLEY@BBNA:HARTLEY  in the user list.

  (4) currently, very little checking is done on the validity of
     the addressee's name. it will just create a file which MAILER
     will complain about

  (5) It does not call MAILER directly. Therefor, the messages may
      not get sent for a while (I believe that MAILER is guaranteed
      to look at every [--UNSENT-MAIL--] file every 24 hours).
      Until I find out how to diddle the mailer, if you want the
      messages to go out immediately, you must run the MAILER program
      yourself.
