This wiki is about anything even remotely related to the programming
language Scheme (see what-is-scheme) and the people that use it.
That is a very general statement, and this wiki is meant to be very
general. It's for, by and about the community that has evolved about
Scheme.
There are in fact quite a few scheme-wikis out there, but they are
mostly centered around the various implementations. The only one that
isn't is The-Scheme-Cookbook which has a pretty narrow mission on
its own.
