    TraveLevel switch controls the general messages. In order to
         receive general trace messages change the value to the
         appropriate level.
         Possible values :
         "0" gives no messages
         "1" gives error messages
         "2" gives errors and warnings
         "3" gives information
         "4" gives verbose information
      
     The default value in WSPBuilder is Information (3).

5.  Note: SPContext in feature activation doesn't work while running the script.
 For that you have to use, workflowproperties.feature as Site(or)Web depending on the feature scope.
