If you really must use long options, write your program in Python and use
its argparse module. It can probably do anything you could want. And write
the rest of your program in Python as well.

However, if you want to be perverse, use it inside your Bash script just to
parse your options and arguments. You would have to devise a way for the
Python part to output something that the Bash part could act on. Perhaps by
perversely using getopts.
