The development of the engine is done via SVN. For those which don't know what SVN is, it's a tool which let you share source code across multiple developer. Basically we develop a code, put it on the SVN repository, and anybody can get it out, or just make sure they do have the latest version. Then if somebody updated / add new files, it can be pushed back to the repository by a simple "commit" command, and every one will get the new files as well as soon as they update their local copy.
