I'd prefer to keep it in.  It has a lot of useful code
and code of historical interest.  Many classic papers
describe or use code that is only easily available in
the Indiana or CMU repositories (for example, I know
of nowhere else to download the Rabbit compiler).

Furthermore, the code tends to actually work in any
modern Scheme, which is more than I can say for any
of the implementation-specific repositories.

schemers.org is a more important site, but it
doesn't actually host any code.

We can move it to the end of the list and mention
it is largely of historical interest, but let's keep it.
