+.Sh DESCRIPTION
+The
+.Nm
+utility extracts keywords from
+.Ux
+manuals and indexes them in a database for fast retrieval by
+.Xr apropos 1 ,
+.Xr whatis 1 ,
+and
+.Xr man 1 Ns 's
+.Fl k
+option.
+.Pp
+By default,
+.Nm
+creates a database in each
+.Ar dir
+using the files
+.Sm off
+.Sy man Ar section Li /
+.Op Ar arch Li /
+.Ar title . section
+.Sm on
+and
+.Sm off
+.Sy cat Ar section Li /
+.Op Ar arch Li /
+.Ar title . Sy 0
+.Sm on
+in that directory.
+Existing databases are replaced.
+If a directory contains no manual pages, no database is created in that
+directory.
+If
+.Ar dir
+is not provided,
+.Nm
+uses the default paths stipulated by
+.Xr man.conf 5 .
+.Pp
+The arguments are as follows:
+.Bl -tag -width "-C file"
+.It Fl a
+Use all directories and files found below
+.Ar dir ... .
+.It Fl C Ar file
+Specify an alternative configuration
+.Ar file
+in
+.Xr man.conf 5
+format.
+.It Fl D
+Display all files added or removed to the index.
+With a second
+.Fl D ,
+also show all keywords added for each file.
+.It Fl d Ar dir
+Merge (remove and re-add)
+.Ar
+to the database in
+.Ar dir .
+.It Fl n
+Do not create or modify any database; scan and parse only,
+and print manual page names and descriptions to standard output.
+.It Fl p
+Print warnings about potential problems with manual pages
+to the standard error output.
+.It Fl Q
+Quickly build reduced-size databases
+by reading only the NAME sections of manuals.
+The resulting databases will usually contain names and descriptions only.
+.It Fl T Cm utf8
+Use UTF-8 encoding instead of ASCII for strings stored in the databases.
+.It Fl t Ar
+Check the given
+.Ar files
+for potential problems.
+Implies
+.Fl a ,
+.Fl n ,
+and
+.Fl p .
+All diagnostic messages are printed to the standard output;
+the standard error output is not used.
+.It Fl u Ar dir
+Remove
+.Ar
+from the database in
+.Ar dir .
+If that causes the database to become empty, also delete the database file.
+.El
+.Pp
+If fatal parse errors are encountered while parsing, the offending file
+is printed to stderr, omitted from the index, and the parse continues
+with the next input file.
+.Sh ENVIRONMENT
+.Bl -tag -width MANPATH
+.It Ev MANPATH
+A colon-separated list of directories to create databases in.
+Ignored if a
+.Ar dir
+argument or the
+.Fl t
+option is specified.
+.El
+.Sh FILES
+.Bl -tag -width Ds
+.It Pa mandoc.db
+A database of manpages relative to the directory of the file.
+This file is portable across architectures and systems, so long as the
+manpage hierarchy it indexes does not change.
+.It Pa /etc/man.conf
+The default
+.Xr man 1
+configuration file.
+.El
+.Sh EXIT STATUS
+The
+.Nm
+utility exits with one of the following values:
+.Pp
+.Bl -tag -width Ds -compact
+.It 0
+No errors occurred.
+.It 5
+Invalid command line arguments were specified.
+No input files have been read.
+.It 6
+An operating system error occurred, for example memory exhaustion or an
+error accessing input files.
+Such errors cause
+.Nm
+to exit at once, possibly in the middle of parsing or formatting a file.
+The output databases are corrupt and should be removed.
