-.SH SYNOPSIS
-.B get_message
-[
-.BI -z[ephyr]
-] [
-.BI -n[ew]
-] [
-.BI -l[ogin]
-]
-.SH DESCRIPTION
-.I get_message
-finds the Athena Global Message server, requests the current message,
-and displays it if necessary. If any errors occur, a cached copy is
-consulted.
-.TP 12
-.B \-z[ephyr]
-indicates that the message (if any) should be displayed as a Zephyr
-Windowgram (see
-.I zephyr(1)
-for details.)
-.TP
-.B \-n[ew]
-indicates that the message should be only be displayed if the user has
-not seen it before.
-.TP
-.B \-l[ogin]
-is normally passed to
-.I get_message
-by
-.I /bin/login
-to indicate that the user might not see this message, and that it
-should not be considered when the
-.I \-new
-argument is later used.
-.SH FILES
-.TP 12
-.B ~/.message_times
-to hold the version number of the last message seen by the user.
-.TP
-.B /var/cache/libgms/messages
-to hold the cached copy of the message during network outages.
-.SH SEE ALSO
-zephyr(1), zwrite(1)
