<Content of myfile.txt>Tweak cpaste.conf to your liking, look at Carbon for the options.
Most likely you only want to change the port.
Copy example_settings.lua to settings.lua, change everything you need to change in there.
Make sure Redis runs on the specified address in settings.lua
Get Carbon itself and run carbon --config=cpaste.conf in the source directory.
