+.Sh DESCRIPTION
+.Nm
+strips the NAME lines from compiled or raw
+.Xr man 1
+pages and creates a whatis.db database for use in
+.Xr apropos 1 ,
+.Xr whatis 1 ,
+or with
+.Xr man 1 Ns 's

+option.
+Man pages compressed with
+.Xr compress 1
+and
+.Xr gzip 1
+are uncompressed before processing.
+.Pp
+When
+.Ar manpath
+is provided multiple times, the resulting database file
+is generated in the first directory specified, and contains
+entries for all the directories.
+.Pp
+If
+.Ar manpath
+is not provided,
+.Nm
+parses
+.Pa /etc/man.conf
+and regenerates the whatis database files specified there.
+Each database file is assumed to reside in the root of the appropriate
+man page hierarchy.
+.Pp
+The options are as follows:
+.Bl -tag -width XCXfileXX
+.It Fl C Ar file
+Use
+.Ar file
+(in
+.Xr man.conf 5
+format) as configuration file instead of the default,
+.Pa /etc/man.conf .
+.It Fl f
+Don't spawn child processes to generate the individual database files,
+but do all the work synchronously in the foreground.
