I do the same thing as what Scott identified above. I use sys.sql_modules and other system tables to help me on such tasks. Just be aware that comments will frequently give false returns when searching for common names like "Client" or "User(s)" or "Employee(s)", etc.
Heh... but, not to worry. According to a lot of the code I've seen, comments won't interfere because (unfortunately) so few people actually use them. 😛
