Usage: migrate_whiteboard_keyword.pl [--remove|-r] [--help|-h] [--doit]
E.g.: migrate_whiteboard_keyword.pl --remove --doit "good first bug" "good-first-bug"
This script will add the specified keyword to any bugs that
contain a string in the status whiteboard. If the --remove option is
given, then string will be removed from the whiteboard as well.
Pass --doit to make the database changes permanent.
