This library gives you two functions to make it easy for your addon to communicate with other players having a compatible addon:

function GlobalComm_Send(id, info, version)
function GlobalComm_Listen(id, func, version, filterown, minversion)

See the documentation in readme.txt file for details

Important notes:
- Requires one free channel for communication. No matter how many addons you have using this library, you still only need that one channel.
- When using strings, beware that the use of special symbols is not recommended. Anything 'weird' might either be lost or generate an error in the library. A known problem is the pipe-symbol | which generates an error if not properly escaped. There are 23 supported letters with accents, umlauts, tildes, dots or circonflexes. See mappings.lua for the full list.
