Implemented item pickup/dropping/equipping. ...

Also expanded the test world and some other adjustments.

Refactored define commands, started integrating monsters into the game world.

Finished the 'goto', 'place' and 'help' commands. ...

I noticed that the code is starting to look quite crufty - time
for a clean up, I think...

Started implementing in-game commands, expanded test world.

Created an ATL-mode for Emacs and expanded the test world.

Added races and character classes, wrote safe-guard against circular imports.
