A (basic) client/server chat system made with Python and Cap'n'Proto!
You will need to install python-dev if you're on a Debian-based system.
Installing capnproto and pycapnp should then be as simple as running $ pip install --user -r requirements.txt.
Once this is done, you should be able to start the client with $ python client.py.
Set your nickname with /nick <my_nickname>, then come join the general room /join general and say hello! :-)
