layer. My new files already take advantage of the abstraction layer
though no attempt is made to port the existing files: this is sheduled
for a future v0.40 release (see http://beta.drop.org/docs/roadmap.php).
Anyway, with the abstraction layer it should be theoretically possible
to run drop on top of every database, even on top of a home-brewed
file-based system. *wink-to-UnConeD* ;-)
