plcm 0.0.0a3

Alternative, pure-python implementation of lcm.

pylcm

This project is a pure-python implementation of lcm's netcode. It is not a drop-in replacement. Instead, it provides alternative and (ideally) more Pythonic interfaces. However, it is meant to be interoperable with any other lcm client over the network.

Over time, some of the tools like lcmgen or lcm-spy may be reimplemented here in Python, but the primary focus is on the netcode and idiomatic implementations of that netcode.
