The Classroom Activity Utility (CAU) helps teachers to create and revise classroom activities. CAU can use an author's master version of an activity to generate versions for students and teachers. Specifically, CAU will:
- Remove sample answers and teacher notes within the activity
  (anything in a selected paragraph style).
- Remove teacher information at the start and end of the activity
  (anything before and after selected tags).

CAU has other features in development. See the web page for details.
