If you want to contribute (implement something from the current list, or
anything), contact the developer's mailing list ...,
in order to avoid having people working on the same thing.

Current list:
+ Audit the code
+ C structure generation instead of a single array
- Add the checking of default value (e.g. 'INTEGER DEFAULT v1')

(+) Means high priority
(*) Means medium priority
(-) Means low priority (ie. nobody is interested to develop that)
