  26  * Preamble: Our main job is to build a nice interface from the modules config

  28  *   user to the data contained in this interface so that when/if he decides to
  29  *   apply his changes we can quickly commit them into the modules config
  30  *   structure. (for this last task we use a GHashTable to accumulate the
  31  *   changes. To commit them, we then just have to circle through it )
