+.Os "Mac OS X"
+.Sh NAME
+.Nm zprint
+.Nd show information about kernel zones
+.Sh SYNOPSIS
+.Nm
+.Op Fl cdhlLstw
+.Op Ar name
+.Sh DESCRIPTION
+.Nm
+displays data about Mach zones (allocation buckets). By default,
+.Nm
+will print out information about all Mach zones. If the optional
+.Ar name
+is specified,
+.Nm
+will print information about each zone for which
+.Ar name
+is a substring of the zone's name.
+.Pp
+.Nm
+interprets the following options:
+.Pp
+.Bl -tag -width "disable -"
+.\" -c
+.It Fl c
+(Default)
+.Nm
+prints zone info in columns. Long zone names are truncated with
+.Ql \&$ ,
+and spaces are replaced with
+.Ql \&. ,
+to allow for sorting by column. Pageable and collectible zones are shown with
+.Ql \&P
+and
+.Ql \&C
+on the far right, respectively. Zones with preposterously large maximum sizes
+are shown with
+.Ql ----
+in the max size and max num elts fields.
+.\" -d
+.It Fl d
+Display deltas over time, showing any zones that have achieved a new maximum
+current allocation size during the interval. If the total allocation sizes are
+being displayed for the zones in question, it will also display the deltas if
+the total allocations have doubled.
+.\" -h
+.It Fl h
+(Default) Shows headings for the columns printed with the
+.Fl c
+option. It may be useful to override this option when sorting by column.
+.\" -l
+.It Fl l
+(Default) Show all wired memory information after the zone information.
+.\" -L
+.It Fl L
+Do not show all wired memory information after the zone information.
+.\" -s
+.It Fl s
+.Nm
+sorts the zones, showing the zone wasting the most memory first.
+.\" -t
+.It Fl t
+For each zone,
+.Nm
+calculates the total size of allocations from the zone over the life of the
+zone.
+.\" -w
+.It Fl w
+For each zone,
+.Nm
+calculates how much space is allocated but not currently in use, the space
+wasted by the zone.
+.El
+.Pp
+Any option (including default options) can be overridden by specifying the
+option in upper-case; for example,
+.Fl C
+overrides the default option
+.Fl c .
