+@chapter Overview
+
+This a daemon spawns a process and reaps all orphaned
+grandchildren. This is useful if you want to keep
+your process tree clean. For instance if you want
+all programs started from inside the same display
+server instance to appear to be inside that display
+if you look inside the process tree, rather than all
+processes that loses their parent being reparented
+to PID 1 and make a mess on your process tree.
+
+
+
+@node Invoking
+@chapter Invoking
+
+@command{orphan-reaper} recognises one option:
+
+@table @option
+@item --fatal
+If this option is used, @command{orphan-reaper}
+will return with exit value 2 if it is unable
+to set up a subreaper. If this option is not
+used, @command{orphan-reaper} will proceed to
+start the specified command even if it cannot
+create a subreaper under it.
+@end table
+
+After the optional option you should specify
+a command in the same mannar as you would
+start it normally. If the command starts
+with a dash (-) you must add the argument
+@option{--} before it.
+
+Once @command{orphan-reaper} has configured
+itself to be a subreaper and spawned the
+specified command it will reexecute into
+@command{reapd} (a libexec) to save memory,
+@command{reapd} does nothing at all except
+reaping children (processes that they before
+their parent are automatically reparented
+by the kernel to be a child of @command{reapd}),
+and exit with exit value 0 when it no longer
+have any children (at which point it cannot
+get any new children). It will also print
+exit with exit value 2, after it has printed
+an error message, if it encounters an error.
