I've had enough requests over the years for this, so it is indeed supported, and I believe there is a need. Quite often people have important programs that for some minor reason don't work on a newer version yet and they can't find the person or the time to fix it. Python's standard installation makes this possible. You can have only one "python" but you can request a specific version by appending the "major dot minor" part of the version number, e.g. python1.5, python2.0, python2.1, python2.2. "python" is a hard link to one of these. You can't (easily) have multiple version with the same major.minor, but that should never be needed. I've heard though that some Linux distributors break this versioning scheme in favor of their own. > If there's a real world need for this, then, yes, we had to come up with > a completely different setup.
