You are correct, the Squaak tutorials are slightly outdated. You
probably want to use the

tools/dev/create_language.pl

script instead of mk_language_shell.pl . create_language.pl creates a
language shell with our newer toolset. To be fair, there are not very
good docs yet for our newer tools. This mailing list is the best place
to ask further questions. I have been meaning to write a guide for our
newer tools and your questions really highlight this. Please let us
know how create_language.pl works for you.


Good luck and have fun!
