This explains the reluctance to fix optparse. In 2007 however python 2.7
wasn't really that common though

Most of my code has to run on python 2.5 / 2.6.

I just checked, that argparse can be installed (pip install argparse)
(didn't check functionality though) for python 2.5 / 2.6

So depending on the situation I had to decide whether I oblige users of
my scripts to  install argparse or whether I stick with optparse and
just add Tim's custom formatter.

Probably I'll go for optparse and Tim's custom formatter for tiny
scripts with no dependencies except standard libraries and
for  argparse for new bigger projects with external module dependencies.
