 .Sh NAME
 .Nm dynamic_pager
-.Nd external storage manager for dynamic pager
+.Nd swap configuration daemon
 .Sh SYNOPSIS
 .Nm dynamic_pager
 .Op Fl F Ar filename
-.Op Fl S Ar filesize
-.Op Fl H Ar high-water-trigger
-.Op Fl L Ar low-water-trigger
-.Op Fl P Ar priority
 .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.
-It is 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.
 .Sh OPTIONS
 .Bl -tag -width Ds
 .\" ==========
 .It Fl F
 The base name of the
 .Ar filename
-to use for the external paging files.  By default this is
+to use for the swapfiles.  By default this is
 .Pa /private/var/vm/swapfile .
 .\" ==========
-.It Fl H
-If there are less than
-.Ar high-water-trigger
-bytes free in the external paging files, the kernel will signal
-.Nm dynamic_pager
-to add a new external paging file.
-.\" ==========
-.It Fl L
-If there are more than
-.Ar low-water-trigger
-bytes free in the external paging files, the kernel will coalese in-use pages
-and signal
-.Nm dynamic_pager
-to discard an external paging file.
-.Ar Low-water-trigger
-must be greater than
-.Ar high-water-trigger
-+
-.Ar filesize .
-.\" ==========
-.It Fl P
-This option is currently unimplemented.
-.\" ==========
-.It Fl S
-The fixed
-.Ar filesize
-[in bytes] to use for the paging files.  By default
-.Nm dynamic_pager
-uses variable sized paging files, using larger sized files as paging demands
-increase.  The
-.Fl S ,
-.Fl H
-and
-.Fl L
-options disable that default and cause
-.Nm dynamic_pager
-to use a series of fixed sized external paging files.
