Sorry if it's unclear...
It started out as a way to run a script at applevel, capture its output,
and compare it with a known good result (presumably generated from
CPython). I was inspired by the original parts of the CPython regression
test framework. The thought was to make a simple way of testing app
level functionality, without having to support a whole unittest
framework at applevel.
app_level_diff.py is the tool that does the running and comparing. The
scripts in scripttest/test are unittests that fit in with the general
testing framework to run the (applevel) scripts in the scripttest
directory proper and compare the results to the pregenerated output
files found there.
So the usage examples are in the scripttest/test directory. - It's
another way of adding tests to pypy, and checking that pypy works like

Hmmm ... you're probably right that it's a poor place for it to live.
But I'm not sure it should be in any particular subdirectory - the tests
exercise the whole of pypy, not just a particular part. As for putting
them in scr/scripttest or so, I was hoping that this would be able to be
a part of the regression testing framework, and would be hit by the

consequence, if people so desire.
P.S. In retrospect, I probably rushed checking in the code. Upon
reexamination, it is rather rough, and not as extensible as I would
like. If I have time this weekend, I'll see if I can improve it. (This
includes adding better documentation.)
