How difficult do you think it would be to write the reverse tool,
converting a .pck.st to MCZ? I'm thinking of something that could say
"I depend on this repository, at this commit id" and grab something
from github. The user just sees an MCZ. I suspect the hard part is the
fact that an MCZ has a UUID identifier and a funny name. Something
would need to remember that this tag in the git repository mapped to
this (UUID, author, version number) triple. A masochist would suggest
storing that in the tag itself...
