C<juv2adult.pl> - Suggests that you read this help. :)

C<juv2adult.pl> -branch=<branchcode> -fromcat=<categorycode> -tocat=<categorycode>  - Processes a single branch, and updates the patron categories from fromcat to tocat.

C<juv2adult.pl> -fromcat=<categorycode> -tocat=<categorycode> -v -n - Processes all branches, shows all messages, and reports the patrons who would be affected. Takes no action on the database.
