Thanks to Retropikzel's initiative, we've been picking up the slack on
updating Docker containers for Scheme implementations. The work is going
on at https://github.com/scheme-containers/monorepo. I hope to make the
web page at https://containers.scheme.org/ more presentable.

He is also interested in CI, and went as far as to set up a Jenkins
instance on a VPS. The discussion is here:
https://github.com/scheme-containers/monorepo/issues/12. CI is something
several people have desired to have under scheme.org, myself included.
Let us know if you want us to move the discussion from GitHub to the
schemeorg mailing list.
