A Library for Programming A Client And Server
ALPACAS is a Web server that can reload itself, XMonad-style, and has the ability to write its own configuration file. The idea is that it will be a development environment that's inherently extensible, like emacs, except using a modern platform (the Web).
It's currently pre-alpha, so you'll likely have to hack the code to get it to run at all. Look for documentation on the Hackage package dyre to get started with customizing it.
See TODO for what's coming next.
