This was something that probably should've been done or at least attempted a long time ago. Making a client that is as good as the existing ones may take quite a bit of effort, but getting one that is usable & can perhaps stir up some interest/and inspire enough effort to complete the task. We shall see. I'll update this once there's some code up.
Code has now been added and it is possible to use the client on the mangband server. Please do not use this with a high-level/main character--there are no macros & anything might happen at this stage. Otherwise, please try it out.
An initial version was released on 31/01/2012. This contains enough to play & test the basic game; nothing more. Many features are missing.
