It'd be great to have a go at implementing OTP style behaviours (a la gen_server, supervisor, etc) now that distribute-process is stable (looking). I'm quite happy to contribute, but there are no contribution guidelines so I'm not sure if I should fork and add a distributed-process-framework sub package to the repository or do this as a separate project or what. Any pointers would be much appreciated.
