+.SH DESCRIPTION
+.IX Header "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
+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 \fBdbmopen()\fR
+can still do so, but new ones can reorder \f(CW@ISA:\fR

+.Vb 2
+\&    BEGIN { @AnyDBM_File::ISA = qw(DB_File GDBM_File NDBM_File) }
+\&    use AnyDBM_File;
+.Ve
+.PP
+Having multiple DBM implementations makes it trivial to copy database formats:
+.PP
+.Vb 4
+\&    use Fcntl; use NDBM_File; use DB_File;
+\&    tie %newhash,  \*(AqDB_File\*(Aq, $new_filename, O_CREAT|O_RDWR;
+\&    tie %oldhash,  \*(AqNDBM_File\*(Aq, $old_filename, 1, 0;
+\&    %newhash = %oldhash;
