Revision 25638

   <action dev="CZ" type="update">
     Moved scratchpad into an own block. This allows that code in the
     scratchpad can depend on other blocks. The scratchpad can now also
     have own configurations.
   </action>
   <action dev="CZ" type="update">
     Extended the build system. If one block depends on the other it 
     can now also use the libraries of the other block. This avoids
     moving the libs to the lib/optional directory.
