Many years ago I wrote toy hashes based on ZODB and MetaKit. Registering
them with anydbm was easy:
import anydbm
anydbm._names.insert(len(anydbm._names)-1, ['ZODBhash', 'MKhash'])
# Insert before dumbdbm
More complex part was to make whichdb to recognize those hashes. I just
monkey-patched whichdb. If I were doing this now I'd do something similar
to atexit module - every hash module will register its own test function,
and whichdb will call them in turn until it finds which db it is.
