I had asked a few weeks ago about how to deal with multiple dbm type databases,
my application needing to talk to 4 dbms more or less at the same time.
I have to thank Chris Torek for his suggestions below of using mdbm, which
should work very nicely with my application. Maybe someone else on the net
can use this into as well. -dave
