Well, the installer will adjust it to point to the version that it
installs, which is the usual thing to do. You can adjust it to
whichever version you want to be considered "Current" afterwards.

Ideally, yes. Unfortunately, a number of tools rely on the framework
being named "Python.framework" and are difficult to configure to deal
with a different framework name. So we use Python.framework and a
version number equal to EPD's version. That still gets us in trouble
with a few tools that try to infer the Python version number from the
framework version number, but I've only encountered one or two, and
those were easy to patch to look up the version number robustly.

Because it's what the "normal python" installer would do too. If I had
a www.python.org installation of Python 2.6 that Current pointed to,
and then I installed the www.python.org Python 2.7, Current would get
updated to 2.7 without asking me. EPD's installer just does the same
thing. It's what every installer of frameworks does that I've ever
seen. They expect that if you explicitly install a framework, that you
want it to be Current.
