If you run a reasonably recent Emacs with HOME-environment variable set to this directory, then you it should lambda the Emacs. Requires Standard ML. Like probably nice if it's available in PATH and you can start it with sml. (It works with SML/NJ. Maybe it works with other SMLs, but that's like impossible to know.)
It:
- randomly overrides probably really useful Emacs keybindings with generally less useful ones
- lets you do some lambda stuff hopefully (it should open a buffer with like mild instructions in it when starting)
- a capybara
- or: a pretty neat error, if your Emacs doesn't png-support
