Launching different interpreters

[Johan Fredrik Ohman]

Hi, I'd like to use the newest interpreter if available. I tried a little
bash scripting, but with no success.
Is there some easy way to check a list of possible interpreters and path,
and when found run the script with that program?

Something like this:
#!/usr/bin/python2.3
If not found:
#!/usr/bin/python2.2

#!/bin/bash, then write a shell script that searches for versions of
Python, execs the most recent one with your Python source.

Speaking as a use, I'd much rather just be able to specify the Python
version to use at install-time (Perhaps by typing "python<VERSION> setup.py
install").
