[Chicken-users] New leveldb eggs

[Caolan McMahon]

I published leveldb bindings a while ago. It turns out the
implementation had some issues with mangled keys in some
circumstances. I've now fixed these issues and created some additional
eggs to compliment leveldb. The new eggs are as follows:

level - provides the leveldb interface (put/get etc)
https://github.com/caolan/chicken-level

leveldb - an implementation of the 'level' api, using libleveldb to store data
https://github.com/caolan/chicken-leveldb

sublevel - an implementation of the 'level' api which provides
namespaced access to another implementation
https://github.com/caolan/chicken-sublevel

I'm hoping to write (or encourage someone else to write) a memory-only
implementation of the 'level' API, which would be useful for testing
or other circumstances where you want to use a module written to the
'level' interface without persisting data.

A small backwards compatibility note on the `level` API - the
`db-stream` procedure now returns a lazy-seq instead of requiring a
thunk which accepts a lazy-seq. It uses set-finalizer! to clean up the
iterator after you've finished with the lazy sequence.

If someone could add the new `level` and `sublevel` eggs to the egg
index that would be great!

Thanks,
