Description Justin Mason 2006-07-09 15:56:41 UTC 
http://rt.cpan.org/Public/Bug/Display.html?id=13353 describes $db->upgrade(), an
API on BerkeleyDB to perform database upgrades; it might be an idea at some
stage to add code which will attempt to upgrade unreadable db database files.

However, this would require us to use the BerkeleyDB perl module instead of
DB_File...  If we were going to support the new module, we may as well make a
full BayesStore module for it.  I believe we'd get several other benefits as
well related to locking, etc.

(I'm pretty sure BerkeleyDB was discussed before and we decided to stick with
DB_File, but it may be worth looking at the idea again.)
