Converting MML to NSF. Is there an easy way?

The other day I found a program called MIDI2MML: https://www.cs.cmu.edu/~tom7/midimml/
However, the site that stored information how to convert MML to NSF, was closed. Copies of the page, apparently, nowhere.
So I want to ask - is there any other software, it is desirable is easier, with the help of which it would be possible to convert MML to NSF?

Tools to compile various MML dialects to NSF include MCK (guide) (and its successor PPMCK) and Pently. But because MML syntax isn't standardized, expect to hand-edit the output of the standard MIDI file decompiler to meet a particular program's requirements. Or if you can find a way to decompile a standard MIDI file to a LilyPond score, you should be able to copy and paste the note data into a Pently score, as Pently's input format is some hybrid of MML and LilyPond syntax.

Could you tell me how to register commands in the midi2mml program?
