Umm, well it'd be cool. And it's also kind of to satisfy my intellectual hunger/curiosity. I had never heard of zLinux before, but now I've read a thing or two about it. > Albert-Jan asks because his package is an interface to an external binary > library, and the location of that library differs according to the platform: Yes, exactly right. It's cool if it just works for all supported platforms. >https://bitbucket.org/fomcl/savreaderwriter/src/09b9c82406e82d43223d6610ba9cbfbf234b16d4/savReaderWriter/generic.py?at=master > > By the way, I don't know that changing directory is a good idea, if you can > avoid it at all.

The chdir may very well be only needed on Windows. I'd have to test this (in sofar as I've access to any of these platforms). I like the fact that, under Windows, things work out of the box, without needing to modify PATH. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
