 The

 .Sh DESCRIPTION
 The
 .Nm dynamic_pager

-daemon manages a pool of external swap files which the kernel uses to
-support demand paging.  This pool is expanded with new swap files as load on
-the system increases, and contracted when the swapping resources are no
-longer needed.  The
-.Nm dynamic_pager
-daemon also provides a notification service for those applications which
-wish to receive notices when the external paging pool expands or contracts.
+daemon can be used to specify a base name for swapfile names using the "-F" command line option or by modifying the configuration plist file.
