+GMSGS IS A PROGRAM TO MAKE IT CONVENIENT TO READ
+SYSTEM MESSAGES. IT IS DESIGNED TO BE PUT IN .DDT. (INIT)
+FILES, AND SETS THINGS UP SO THAT RMAIL MAY BE USED
+TO VIEW THE SYSTEM MESSAGES AS WELL AS A USER'S OWN MAIL.
+(SEE .INFO.;RMAIL ORDER FOR HOW TO USE RMAIL).
+
+GMSGS IS INVOKED FROM DDT WITH THE COMMAND
+
+	:GMSGS <USERNAME>
+
+OR
+
+	:GMSGS
+
+WHICH DEFAULTS <USERNAME> TO YOUR <XUNAME> (YOUR SELF).
+GMSGS LOOKS ON THE .MSGS.; DIRECTORY FOR ANY NEW FILES, AND
+COPIES THEM INTO <USERNAME>'S MAIL FILE
+(<USERNAME>;<USERNAME> MAIL OR COM:<USERNAME> MAIL).
+(IF "/M" APPEARS IN THE COMMAND STRING, THEY ARE MAILED TO
+<USERNAME> THROUGH THE COMSAT INSTEAD OF DIRECTLY, SO THAT ANY
+FORWARDING, ETC. THAT THE USER HAS REQUESTED WILL TAKE PLACE).
+NORMALLY, THE COPIED FILES APPEAR AT THE FRONT OF THE MAIL FILE
+IN REVERSE CHRONOLOGICAL ORDER, EACH PRECEDED
+BY ITS NAME AND FOLLOWED BY A ^_. HOWEVER, IF "/R"
+APPEARED IN THE COMMAND LINE, THE MESSAGES GO AT THE
+END OF THE MAIL FILE IN FORWARD CHRONOLOGICAL ORDER.
+WHEN "/M" IS USED, "/R" CONTROLS ONLY THE ORDERING OF THE MESSAGES;
+THE USER'S MAILING OPTIONS DETERMINE WHETHER THEY GO AT THE
+BEGINNING OR THE END OF ANY MAIL FILE.
+
+THE COMMAND STRING MAY ALSO SPECIFY THE NAMES OF THE MACHINES
+WHOSE MESSAGES ONE WISHES TO SEE.  THEY SHOULD BE SPECIFIED
+BY GIVING THE NAMES OF THE MACHINES, EACH PRECEDED BY A "*",
+AS IN "*AI", OR "*ML".  "*" BY ITSELF SPECIFIES ALL MACHINES.
+IF MACHINE NAMES ARE NOT SPECIFIED, THE DEFAULT IS O SHOW
+ONLY THE MESSAGES OF THE MACHINE GMSGS IS RUNNING ON.
+EXAMPLE:  :GMSGS JRL *ML *MC<CR> WOULD GIVE JRL ALL NEW
+MESSAGES INTENDED EITHER FOR ML OR FOR MC.  IT COULD BE
+RUN ON ANY I.T.S. SYSTEM AND STILL ACHIEVE THAT RESULT.
+:GMSGS * RMS <CR> GIVES RMS ALL MESSAGES INTENDED FOR ANY I.T.S.
+(NOTICE THAT THE ORDER OF THE USER NAME AND MACHINE NAMES
+IS IRRELEVANT).
+
+A MESSAGE FILE IS "NEW"
+IF IT HAS APPEARED SINCE THE LAST TIME GMSGS WAS
+USED (OR, THE DDT COMMAND :MSGS WAS USED) BY USER
+<USERNAME>. THIS CAUSES EACH FILE THAT APPEARS ON THE
+.MSGS.; DIRECTORY TO BE PROCESSED EXACTLY ONCE BY EACH
+USER.
+
+IF THERE ARE NO NEW MESSAGES, GMSGS PRINTS NOTHING AND
+WRITES NO FILES. IF THERE ARE MESSAGES, GMSGS REWRITES
+THE MAIL FILE AND TYPES OUT "(THERE ARE MESSAGES)".
+THE TYPEOUT CAN BE INHIBITED BY PLACING "/S" IN THE COMMAND
+STRING.
+
+IF THE /N SWITCH IS SPECIFIED, THEN GMSGS, IN ADDITION TO ITS
+NORMAL FUNCTIONS, ANNOUNCES THE ARRIVAL OF MAIL.  IF THE
+USER'S MAIL FILE IS MORE RECENT THAN HIS _MSGS_ FILE, INDICATING
+THAT MAIL HAS ARRIVED SINCE THE PREVIOUS GMSGS,
+"(THERE IS MAIL)" IS PRINTED.
+
+GMSGS RETURNS WITH .BREAK 16,340000 IF THERE WERE MESSAGES;
+WITH .BREAK 16,140000 IF THERE WERE NONE.
+
+THE /D SWITCH CAUSES THE DISTRIB AND EXPIRES SPECIFICATIONS TO BE
+INCLUDED WITH MESSAGES WHEN THEY ARE WRITTEN INTO THE MAIL FILE.
