#pod =head1 OVERVIEW
#pod
#pod This class exists almost entirely to allow C-checking.  It provides a
#pod C method that returns a blessed, empty object.  Passing it any parameters
#pod will cause an exception to be thrown.
#pod
#pod A C method is also provided, which turns a vaguely
#pod filename-like string into a safer filename string.
