Am actually making reasonable progress. Have parsed my manuel, and got a spreadsheet, and got the most recent monsters.txt I could find from the latest changes. Now facing a few decision points.
Firstly, shall we use the Manuel Phylum names or the current ones ? ie. Manuel has dude, Mafia has humanoid. Manuel has humanoid, Mafia has demihuman. Manuel has construct, Mafia has object. Manuel has elf, Mafia has crimbo. Manuel has weird, Mafia has strange.
Secondly, do we just want an output of monsters.txt lines that need updating? Shouldn't be hard to do.
