[maemo-developers] Is it possible to make a "well-behaved" pyGame app with maemo-python ?

I hope there's a typos in that filename (missing.indt) or I don't 
understand anything anymore :-)

I think I have tried all possible combinations of with, without (except 
maybe the right one).
There are no two examples anywhere using the same syntax. Consider the 
Python Howto on maemo.org :
http://maemo.org/development/documentation/how-tos/3-x/python_maemo_3.x_howto.html

The recommended .desktop file has :
X-Osso-Service=hello_pymaemo

While the .service file is named hello_pymaemo.service (not 
com.nokia.hello_pymaemo.service), although it contains :
[D-BUS Service]
Name=com.nokia.hello_pymaemo

How consistent is that ? Where is the logic ?

A single, correct, working example in the right place would save 
man-months of hair-pulling.

Okay. Just to be nice :-)
