Create a simple script, foo-script.py
Note that the script starts with a Unix-style '#!' line saying which
Python executable to run. The wrapper will use this line to find the
correct Python executable.

When the copy of cli.exe, foo.exe in this example, runs, it examines
the path name it was run with and computes a Python script path name
by removing the '.exe' suffix and adding the '-script.py' suffix. (For
GUI programs, the suffix '-script.pyw' is added.) This is why we
named out script the way we did. Now we can run out script by running
the wrapper:
This example was a little pathological in that it exercised windows
(MS C runtime) quoting rules:
- Strings containing spaces are surrounded by double quotes.
- Double quotes in strings need to be escaped by preceding them with
back slashes.
- One or more backslashes preceding double quotes need to be escaped
by preceding each of them with back slashes.

Specifying Python Command-line Options
--------------------------------------
You can specify a single argument on the '#!' line. This can be used
to specify Python options like -O, to run in optimized mode or -i
to start the interactive interpreter. You can combine multiple
options as usual. For example, to run in optimized mode and
enter the interpreter after running the script, you could use -Oi:
a,
#!%(python_exe)s -Oi
