Wow, as a former MajorMUD addict (~30 years ago) that's extremely interesting to see. Especially since MajorMUD is rarely discussed on HN, even in MUD or BBS-related threads.

Did you find it worked reasonably well on any portion of the codebase you could throw at it? For example, if I recall correctly, all of MajorMUD's data file interactions used the embedded Btrieve library which was popular at the time. For that type of specialized low-level library, I'm curious how much effort it would take to get readable code.
