+.SH SYNOPSIS

+.br
+.BI /etc/swapon " specialfile " ...
+.br
+.B /etc/swapoff \-a
+.br
+.BI /etc/swapoff " specialfile " ...
+.SH DESCRIPTION
+.B Swapon
+is used to specify devices on which paging and swapping are to take place.
+Calls to
+.B swapon
+normally occur in the system multi-user initialization file
+.I /etc/rc
+making all swap devices available, so that the paging and swapping activity
+is interleaved across several devices and files.
+
+Normally, the first form is used:
+.TP
+.B \-a
+All devices marked as ``sw'' swap devices in
+.I /etc/fstab
+are made available.
+.PP
+.B Swapoff
+disables swapping on the specified devices and files, or on all swap
+entries in
+.I /etc/fstab
+when the
+.B \-a
+flag is given.
