System got merged into Support a long time ago. We could improve the
documentation of what lib/Support is, but this is a good start IMHO.

Ah, ok. In that case, I think that it would be best to make a new page for
libSupport, and have it defer to SystemLibrary.rst for discussion of the
"libSystem" parts of libSupport. The major necessary changes for
SystemLibrary.rst would then be to mention its inclusion in libSupport
(important) and fix file paths (mechanical, less important).

Sorry, but at least for me having a docs/SystemLibrary.rst and so
lib/System is very confusing. Ideally we would have a
docs/SystemLibrary.rst that would just says "this library has been
merged to lib/Support" and docs/SupportLibrary.rst documents whatever
is in lib/Support.
