Make sure that .py file is used, even if .pyc got executed
Make sure that .py file is used, even if .pyc got executed

If python already byte-compiled the source code to .pyc file,
the __file__ points to .pyc, rather than to .py, which breaks the
copying mechanism.

Use regex substitution to make sure we're always copying the original
source file.
