+.Sh DESCRIPTION
+.Nm Ipcrm
+removes the specified message queues, semaphores and shared memory
+segments.  These System V IPC objects can be specified by their
+creation id or any associated key.
+.Pp
+The following options are used to specify which IPC objects will be removed.
+Any number and combination of these options can be used:
+.Bl -tag -width indent
+.It Fl M Ar shmkey
+Mark the shared memory segment associated with key 
+.Nm shmkey
+for removal.
+This marked segment will be destroyed after the last detach.
+.It Fl m Ar shmid
+Mark the shared memory segment associated with id 
+.Nm shmid
+for removal.
+This marked segment will be destroyed after the last detach.
+.It Fl Q Ar msgkey
+Remove the message queue associated with key 
+.Nm msgkey
+from the system.
+.It Fl q Ar msqid
+Remove the message queue associated with the id
+.Nm msqid
+from the system.
+.It Fl S Ar semkey
+Remove the semaphore set associated with key
+.Nm semkey
+from the system.
+.It Fl s Ar semid
+Removes the semaphore set associated with id
+.Nm semid
+from the system.
+.El
+.Pp
+The identifiers and keys associated with these System V IPC objects can be
+determined by using
