No, that affects the string printed only *after* the "usage = " string.
 What I would like to do is insert some string *before* the "usage = "
string, which is right after the command I type at the command prompt.
So I would like to make it look like this:

% myprog.py -h
************ THIS IS NEWLY INSERTED STRING ************
usage: myprog.py [options] input_file


options:
  -h, --help             show this help message and exit
  -v, --verbose        print program's version number and exit
  -o FILE               Output file
