I don't mean anything about VMs. I just mean something like what Python's virtualenv does: create a parallel filesystem hierarchy on which you have write permission, where ryppl can do its installations, and then update PATH and other things in the environment before running the tests to simulate the conditions of a normal installation.
Well, that level of isolation would be ideal, and I'd love to use a chroot jail on systems where it's available. However, I think that for some platforms we'll have to settle for something much less ambitious, and I plan to put my attention on the common denominator first, i.e. something that can easily be coded up in portable C++ or Python. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
