+.Sh DESCRIPTION
+.Nm Quotaon
+announces to the system that disk quotas should be enabled on one or more
+filesystems.
+.Nm Quotaoff
+announces to the system that the specified
+filesystems should have any disk quotas
+diskquotas turned off.
+The filesystems specified must have entries in
+.Pa /etc/fstab
+and be mounted.
+.Nm Quotaon
+expects each filesystem to have quota files named
+.Pa quota.user
+and
+.Pa quota.group
+which are located at the root of the associated file system.
+These defaults may be overridden in
+.Pa /etc/fstab .
+By default both user and group quotas are enabled.
+.Pp
+Available options:
+.Bl -tag -width Ds
+.It Fl a
+If the
+.Fl a
+flag is supplied in place of any filesystem names,
+.Nm quotaon Ns / Ns Nm quotaoff
+will enable/disable all the filesystems indicated in
+.Pa /etc/fstab
+to be read-write with disk quotas.
+By default only the types of quotas listed in
+.Pa /etc/fstab
+are enabled.
+.It Fl g
+Only group quotas listed in
+.Pa /etc/fstab
+should be enabled/disabled.
+.It Fl u
+Only user quotas listed in
+.Pa /etc/fstab
+should be enabled/disabled.
+.It Fl v
+Causes
+.Nm quotaon
+and
+.Nm quotaoff
+to print a message for each filesystem where quotas are turned on or off.
+.El
+.Pp
+Specifying both
+.Fl g
+and
+.Fl u
+is equivalent to the default.
