This file contains invisible Unicode characters

This file contains invisible Unicode characters that are indistinguishable to humans but may be processed differently by a computer. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

This directory is used by the ITS mailing system; that is, the QMAIL
and Satellite programs. Please DO NOT EVER delete any file from this
directory; also, the programs therein should not be modified without
first consulting BUG-MAIL. If GC'ing must be done on program files,
do not delete either the most recent or most ancient file (which is
usually around for a reason). Under some circumstances, BURNUP dumps
can gobble up gross amounts of space. In this situation, flushing
intermediate dumps (never first or last) is OK.
The files with particular automated functions are:
ID 69 creation date indicates when current STATS file began.
FROM INQUIR creation date indicates when current INQUIR file written.
LOCK UNIQUE page shared by all comsats for lock-switch functions
LIST MASTER master message list
LIST QUEUE queue information file
LIST REMIND reminders list file
LIST EQVS equivalence table data "compiled" from NAMES
LISTS MSGS holds text of messages in queue.
BURNUP binary dumps of satellites that detect fatal errors.
COMSAT the binary actually loaded and run.
MAIL input to the satellite.
NAMES the ASCII form of the equivalence tables.
STATS statistics and running commentary kept by the satellite.
there also exist parallel sets for experimental versions:
XLOCK XQUEUE XREF XMAIL XNAMES XSTATS etc.
