You are missing the argument though:

ruby1.7 ./ackermann.ruby 7

With '8' even 1.7 fails.

We don't really know Ruby enough to fix things.  Maybe there is a
way...

Posted there too, for the heck of it:-)

Ah... Hrm.  It could probably stand to be reduced to anything that
matches one of the available testnames.  I think I got bit once by it
running a ~ file.

Yes!  Definitely.  I think initially, the two args would be -tests and
-langs so that you could give it a list of tests to run for all
languages, or a list of languages to run all tests for, or only the
intersection of the specified -tests and -langs.

Seems odd to me too.  Does it run ok without 'gr = gen_random' ?

Well, we want to start adding tests too, but if we add a bunch and
then change the framework, it could be a lot of work to fix things up.

You're welcome.
