# 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)>, L<perldbmfilter>.
