Listing scripts
===============
So far we have been dealing with pure and non-pure Python modules,
which are usually not run by themselves but imported by scripts.
Scripts are files containing Python source code, indended to be started
from the command line. Distutils doesn't provide much functionality
for the scripts: the only support Distutils gives is to adjust the
first line of the script if it starts with `#!' and contains the word
"python" to refer to the current interpreter location.
The `scripts' option simply is a list of files to be handled in this
way.
