570 Complete applications rarely belong in the Perl Module Library, Many
571 applications contain some perl code which could be reused, Break-out the
572 reusable code into one or more separate module files, Take the opportunity
573 to reconsider and redesign the interfaces, In some cases the 'application'
574 can then be reduced to a small
