Well, you don't have to launch a pyc file anyway. Put all your code in
some (pyc) modules on the standard Python path, and use a clear-text
script with some trivial code to invoke a function from the compiled
modules.

Otherwise you can customize sys.path a little from your script,
using __file__ and os.path.dirname. Nothing complicated AFAICT.

(by the way, the fact that pyc files are version-specific should
discourage any use outside of version-specific directories,
e.g. /usr/lib/pythonX.Y/site-packages)
