[gcompris-devel] Log Module for gcompris

[Bruno Coudoin]

Ralf, I just looked at your code and it's a good start. Note that I
think we can, based on your code add these feature gcompris wide in one
shot whithout touching the boards themselves. In menu.c the boards are
started and thus we could call your treatment_log_starttime, then from
one level to the other, we can log it in the bonus api and we even know
here if it's a pass or a fail. Last we can log the board quit in the bar
or the bonus.board_finished call.

That's a good oportunity to think about what we need here (stasZ, still
there ?).

With you code, we monitor the time in each board/level. That's a good
start but to be usefull, we need some sucess/failure data and a comment
on what failed so that a teacher can easily read it.

Bruno.
