Zork I, II, and III go Open Source

These games were created by splitting the original mainframe Zork in three parts, because it was much too big to run on a personal computer, and then adding some new bits to each to make them standalone. IIRC the original is already open source (or public domain), though I’m not sure if that’s the original MDL (a Lisp dialect) or the FORTRAN port, or both.

I always wondered how ZIL/MDL/Muddle ended up with those angle brackets rather than a more traditional Lisp syntax. The Introduction in the MDL primer talks a bit about the Lisp heritage but doesn't talk about the reason for the syntax deviation.
