ineedpy2: Library to swap to newer python version on a multi-version system.

============================================================================

Find the latest Python 2 version installed on the system and if this

program is not running on that version, re-invoke it with that version.

Background

----------

One of the problems of a system administrator is that enterprise Linux distros

which ship with, and often require, /usr/bin/python to be a fairly old versions.

For example, Python 2.1.  Applications can be very difficult to write such that

they are happy on Python 2.1 and Python 2.7.  Many of these distros include a

newer Python, but it has to be invoked as "python2.6", for example.

You can change the "#!" line in the script, but this makes packaging

more difficult.

Examples

--------

To make sure you are running on the absolutely latest installed Python 2 on

the system:

    import sys

    print 'Version:', sys.version_info

    import ineedpy2

    ineedpy2.rerunonlatest()

If run on a system with the default Python version being 2.1, but python

2.6 also installed will display:

    Version: (2, 1, 3, 'final', 0)

    Version: (2, 6, 5, 'final', 0)

NOTE: Anything run before the "runonlatestpy2" will be run once on the

older version and once on the newer version.

You can also request the reinvocation only if the python minor version

isn't at least a specific value.  In other words, "I know I need at least

Python 2.4":

    from ineedpy2 import requireminor

    requireminor(4)
