sent by other programs like `reboot`, `shutdown` or other processes like NFS
to warn users when the NFS server terminates.
+Optionally X11 can be used to automatically terminate wall-notify when the
+current X11 session terminates, i.e. when the user logs out. See below.
+
wall-notify is licensed under GPL 3 (or later).
- C89 compiler
- libutempter or utmpx.h (utmpx.x requires a setgid utmp binary)
+- optional: X11 headers and library, necessary for X11 support
+
INSTALLATION
------------
./configure && make && make check
+The libutempter is not available, the binary must be setgid utmp:
+
+ chgrp utmp src/wall-notify
+ chmod g+s src/wall-notify
+
USAGE
-----
The shell is not used when running the program.
+If X11 support is compiled in then the '-X' option can be used to terminate
+wall-notify automatically when the X session quits. This is useful when
+wall-notify is started in `.xinitrc` and should quit when the X session ends,
+i.e the user logs out:
+
+ ./src/wall-notify -X cat
+
+
BUGS
----
+Doesn't work on OpenBSD which has no support for utmpx.h.
