Done.  See Misc/NEWS, Tools/scripts/{pickle2db,db2pickle}.py.  I've gone
back and forth using Python 2.1.3, 2.2.2 and current CVS using the bsddb
stuff, though I haven't tested all the possible database formats and don't
have Python 1.5.2 to try with anymore.  I tried to avoid gratuitous
incompatibilities with older versions of Python, but some extra exercise
using 2.0 and 1.5.2 with different databases would be appreciated.
