With much animation being produced overseas, production companies are having to fax revised script pages to their production studios. As fax machines transmit in black and white, the usual means of identifying sets of revisions by printing them on different colored pages does not work.
To solve this problem, a multi-revision mark standard has been introduced: The first day's revisions have a single asterisk (*), the second day's revisions have two asterisks (**), and so on.
Screenwriter handles this with a Revision Locking Count, which you increase by locking the Current Revision Marks.
