You've hit the proverbial nail with the hammer. The problem is that my

would love to use a nice sh, csh, or bash shell script. My hands are tied
because Windows does not provide such wonderful shells.
*Provides*, no... neither does it provide Python, for what that's
worth. But you can certainly get it (bash):
http://win-bash.sourceforge.net/
I suppose it's not worth installing just for this purpose though...
But you can provide with your application a DoS batch file that does
exactly the same thing (in addition to a shell script). The user
would quite intuitively use whichever were appropriate, or follow your
provided directions otherwise. Or, the equivalent in (hopefully
OS-agnostic) Python:
import os, sys
# I believe this gets the name of the root in all major OSes
def root_dir(path):
if os.path.dirname(path) == path:
return path
return (root_dir(os.path.dirname(path)))
appname = <name of your python script>
root = root_dir(os.getcwd())
install_path = os.path.join(root, "usr")
bin_path = os.path.join(install_path, "bin")
os.environ["PATH"] = bin_path + os.pathsep + os.environ["PATH"]
python_path = os.path.join(bin_path, "python")
args = sys.argv[1:]
args.insert(0, os.path.join(bin_path, appname))
args.insert(0, python_path)
args.insert(0, python_path)
os.execv(python_path, args)
