+# GDBM_File.pm -- Perl 5 interface to GNU gdbm library.
+
+=head1 NAME
+
+GDBM_File - Perl5 access to the gdbm library.
+
+=head1 SYNOPSIS
+
+    use GDBM_File ;
+    tie %hash, 'GDBM_File', $filename, &GDBM_WRCREAT, 0640;
+    # Use the %hash array.
+    untie %hash ;
+
+=head1 DESCRIPTION
+
+B<GDBM_File> is a module which allows Perl programs to make use of the
+facilities provided by the GNU gdbm library.  If you intend to use this
+module you should really have a copy of the gdbm manualpage at hand.
+
+Most of the libgdbm.a functions are available through the GDBM_File
+interface.
+
+=head1 AVAILABILITY
+
+Gdbm is available from any GNU archive.  The master site is
+C<prep.ai.mit.edu>, but your are strongly urged to use one of the many
+mirrors.   You can obtain a list of mirror sites by issuing the
+command	C<finger fsf@prep.ai.mit.edu>.
+
+=head1 BUGS
+
+The available functions and the gdbm/perl interface need to be documented.
+
+=head1 SEE ALSO
+
+L<perl(1)>, L<DB_File(3)>.
