DGD is a rewrite from scratch of the LPMud server. It runs on Windows, MacOS, BeOS and many versions of Unix. This is the core distribution of DGD, providing all the tools needed to implement interactive servers, for instance MUD, IRC, WWW, etc. A reference implementation of a kernel library is provided, which can be further built on. Normally with DGD, there is a kernel library to define the programming environment and a database library to define the interaction environment. Please report bugs to . WWW: http://www.dworkin.nl/dgd/
