   7  * Claws-contacts is a proposed new design for the address book feature
   8  * in Claws Mail. The goal for this new design was to create a
   9  * solution more suitable for the term lightweight and to be more
  10  * maintainable than the present implementation.
  11  *
  12  * More lightweight is achieved by design, in that sence that the whole
  13  * structure is based on a plugable design.
