Upcoming changes in the API
The implementation of versioning/workspace support cannot be accomplished without some changes to the API.
Extension "overlays" has been downloaded only 4 times so far, so I guess a change of API won't break a lot of existing stuff ;-)
Still I wanted to warn those few early adopters (maybe the downloads were just robots, is that possible?) that I'm going to change part of the API to accomodate the needs that are arising while implementing support for versioning/workspaces. I'm sorry for the inconvenience, but I'm sure you'll appreciate the advantages of having a workspace-savvy library.
Some refactoring will also take place.
