[plt-scheme] running the framework tests?

Hi everyone,

I'm making some scary changes to mzscheme's C source, and I want to make
sure I haven't completely broken the runtime.  I'm looking for notes on
how to run the bin/framework-test to test out mzscheme.

At the moment, I haven't been able to figure out how to drive the tests in
collects/tests/mzscheme through framework-test, so as the README suggests,
I've been just doing (load "basic.ss") iteratively till things work out.
Is that what other people do?

This is related to bug 7449.  Thanks!
