"""
Import commented python source, format it for yade.wikia.com by interspersing <source> and literal text in comments.
If given a second files (which is a c++ file), the comments will be taken from the python source,
but the code from the c++ file.
There are special marks for comments in python: "##" for empty line
or "## some text" for non-empty line (the first space is stripped)
Special marks for c++ comments are //@, but their contents is flushed;
they serve merely to synchronize with python comments.
Adjacent comment lines and adjacent code lines will be merged.
Leading tabs in the code are replaced by unicode non-breakable spaces
(<source> would otherwise eat leading spaces of the first line)
Usage 1: generate simple-scene.py formatted for wiki
./py2wiki simple-scene.py
Usasge 2: generate SimpleScene.cpp formatted for wiki with comments from simple-scene.py
./py2wiki simple-scene.py ../extra/SimpleScene.cpp
