Description of the module system of Scheme-48. Found on Jonathan Rees' page https://www.mumble.net/~jar/s48/index.html
I am not sure yet whether Rees' critique [1] on the use of the term "module" applies here.

Snow is a place to share Scheme programs, libraries and data. Currently we host only R7RS libraries, though we may expand to more dialects in the future.

I tried to run the trivial program
 (define ! (n) (if (< n 2) 1 (* n (! (1- n)))))
 (display (! 10))
on http://chibi-scheme.appspot.com/, but got an error message about not being able to enlarge memory arrays.

While this blog article is about a new feature of the Scheme-based Guix Linux package manager, it contans the following interesting observation about erroneous shell settings: "it’s not uncommon for the shell to mess up with the whole environment. Why? Because, contrary to documented practice, it’s quite common for users to define or override environment variables in the startup files of non-login shells, ~/.bashrc for Bash, ~/.zshrc for Zsh. Instead, environment variable definitions should go to the startup file of login shells—~/.bash_profile, ~/.profile, or similar. But let’s face it: it’s a subtle distinction that few of us know or care about."
