Here's something that seems to come up from time to time in Debian.

Take a Python application like tox, nose, or pyflakes. Their executables work with both Python 2 and 3, but require a #! line to choose which interpreter to invoke. When we add Python 3 support in Debian for such a script, all the library installations are handled just fine, but we have conflicts about what to name the thing that lands in /usr/bin. Do we have /usr/bin/pyflakes and /usr/bin/pyflakes3? Do we call the latter py3flakes (as has been convention with some other scripts, but which breaks locate(1))? Do we simply remove the /usr/bin scripts and encourage people to use something like $python -m nose?

How about always running the version specific targets, e.g. nosetests-2.7?
