[Imc-tech] Perl and SA

[Arun Bhalla]

On a whim, I tried db4.0_upgrade, and it seems to work.  (You're right
that db_dump/db4.0_load doesn't work -- I imagine the versions dump
in slightly different formats, and db4.0_load never complains.)

My work is at /tmp/bayes/old.  I imagine you could drop them in place.

\u@\h:\w\$ sa-learn -D --dbpath `pwd`  --dump all |& less
