The link on the right side mentions the Simugraph Roguelike Development Library. However, when I shared that link, I didn't share the link to the actual home page of the Simugraph library. When I checked it out a week ago, however, I discovered something new:

http://www.simugraph.com/h-world/pmwiki/pmwiki.php

Not only is it a Wiki (although you'll have to contact Hansjörg for a password to be able to edit, due to severe spam), but it also has much, much, much more content than the old Simugraph library did.

Read and enjoy!
