So in the spirit of other Scheme topics, and to limit the demands on Arthur, I've created a GitHub Schemetest organization, into which we can put repositories with testing libraries, documentation, examples, etc.  Ideally it will in due course have a working SRFI 64 library for every Scheme implementation people care about, and whatever other testing libraries people like to use.

Don't know if this warrants a Schemetest mailing list, but I'll throw that idea out.
