There is https://github.com/magritte-metamodel/magritte which I forked from.
I wonder if we can make that canonical. It would be easy for me to sync my
changes back and from the README, it appears that most other Smalltalk load
Magritte from elsewhere. Regarding Sqeak, there are the mcz repos, and
IFAICT Squeak has not shown much interest in git, so we're probably safe
there. Either way, please coordinate with me because the StHub repo is
waaaay behind my fork���
