Yes, I meant that. > Perhaps, but realistically I'm not sure it's worth the effort to > make this change because almost the only time we ever run these tests > is when we've rebuilt the make binary, and it's easy enough to run just > a single test if we want to. A few beneifts: - Being part of the make targets, it would enable running them in parallel, taking around 1/4th the time it takes now. - If you run them several times, you only get rerun the ones that failed (especially if you run with -k) or didn't yet run. This allows interrupting the job and restarting (as I did). But of course, I'm not going to tell you all of the benefits that a Makefile has over a shell script. :) Cheers, Alex -- <http://www.alejandro-colomar.es/> GPG key fingerprint: A9348594CE31283A826FBDD8D57633D441E25BB5
