+.Sh SYNOPSIS
+.Nm
+.Op Oo Cm \&+ Oc Ns Ar hhmm

+The
+.Nm
+utility waits until the specified time, then reminds you that you
+have to leave.
+You are reminded 5 minutes and 1 minute before the actual
+time, at the time, and every minute thereafter.
+When you log off,
+.Nm
+exits just before it would have
+printed the next message.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Ar hhmm
+The time of day is in the form
+.Ar hhmm
+where
+.Ar hh
+is a time in
+hours (on a 12 or 24 hour clock), and
+.Ar mm
+are minutes.
+All times are converted to a 12 hour clock, and assumed to
+be in the next 12 hours.
+.It Cm \&+
+If the time is preceded by
+.Sq Cm \&+ ,
+the alarm will go off in hours and minutes
+from the current time.
+.El
+.Pp
+If no argument is given,
+.Nm
+prompts with "When do you
+have to leave?".
+A reply of newline causes
+.Nm
+to exit,
+otherwise the reply is assumed to be a time.
+This form is suitable for inclusion in a
+.Pa .login
+or
+.Pa .profile .
+.Pp
+To get rid of
+.Nm
+you should either log off or use
+.Ql kill \-s KILL
+giving its process id.
