=head1 NAME

AnyDBM_File - provide framework for multiple DBMs

NDBM_File, DB_File, GDBM_File, SDBM_File, ODBM_File - various DBM implementations

=head1 SYNOPSIS

use AnyDBM_File;

=head1 DESCRIPTION

This module is a "pure virtual base class"--it has nothing of its own.
It's just there to inherit from one of the various DBM packages.  It
prefers ndbm for compatibility reasons with Perl 4, then Berkeley DB (See
L<DB_File>), GDBM, SDBM (which is always there--it comes with Perl), and
finally ODBM.   This way old programs that used to use NDBM via dbmopen()
can still do so, but new ones can reorder @ISA:

BEGIN { @AnyDBM_File::ISA = qw(DB_File GDBM_File NDBM_File) }
    use AnyDBM_File;

Having multiple DBM implementations makes it trivial to copy database formats:

use Fcntl; use NDBM_File; use DB_File;
    tie %newhash,  'DB_File', $new_filename, O_CREAT|O_RDWR;
    tie %oldhash,  'NDBM_File', $old_filename, 1, 0;
    %newhash = %oldhash;

See L<DB_File>. 
Requires symbolic links.
