How to synchonize actions and frames in Python scripts ?

Hi !

I am trying to make a script with python, but I don’t understand how to adserve the actions with the frames.
I suppose there is a connection with the options Redraw, Framechanged
or Onload available in the scriptlink panel, but I am not able to synchronize the actions in the code with precise frame number.
I haven’t found anything in the Python Api for Blender, neither in the Blender 2.3 manual except few general informations p574-575.

I need some Help ! Thanks in advance.
