+.TH MK-AMD-MAP 8 "June 28, 1993"
+.SH NAME
+.B mk-amd-map
+\- create database maps for Amd
+.SH SYNOPSIS
+.B mk-amd-map
+[
+.B \-p
+]
+.I mapname
+.SH DESCRIPTION
+.B mk-amd-map
+creates the database maps used by the keyed map lookups in
+amd(8).
+It reads input from the named file
+and outputs them to a correspondingly named
+hashed database.
+.TP
+.B \-p
+This
+option prints the map on standard output instead of generating
+a database.  This is usually used to merge continuation lines
+into one physical line.
+.SH SEE ALSO
+.BR amd (8).
