+
+The typical handler you see in all these modules. Takes $r, the
+http request, as an argument.
+
+The response to the request is governed by two form variables
+
+ form.action form.state response
+ ---------------------------------------------------
+ undefined undefined print main menu
+ upload undefined print courselist upload menu
+ upload got_file deal with uploaded file,
+ print the upload managing menu
+ upload enrolling enroll students based on upload
+ drop undefined print the classlist ready to drop
+ drop done drop the selected students
+ enrollstudent undefined print student username domain form
+ enrollstudent gotusername print single student enroll menu
+ enrollstudent enrolling enroll student
+ classlist undefined print html classlist
+ classlist csv print csv classlist
+ modifystudent undefined print classlist to select student to modify
+ modifystudent selected print modify student menu
+ modifystudent done make modifications to student record
