I hope `jython.py` could replace also `jython` shell script to make start-up consistent on different platforms. Having only one start-up script would also mean less maintenance work.

It would be nice for `jython(.py)` to support also CPython 2.6. The main motivation would be to ease using Jython 2.7 on RHEL 6 (still pretty widely used and supported until 2020) which only has CPython 2.6 by default. It seems that it would mainly require vendoring backports of argparse and OrderedDict (both available on PyPI) and replacing `python2.7` with `python` on the shebang line.

If it's not too much work, it would also be nice to support CPython 3.x. That would also avoid problems using `python` on the shebang with Arch Linux where `python` runs CPython 3. 

If there are no objections, I can take a look at these enhancements myself.
