This perl 5 library uses objects to create Web fill-out forms on the
fly and to parse their contents. It provides a simple interface for
parsing and interpreting query strings passed to CGI scripts. However,
it also offers a rich set of functions for creating fill-out
forms. Instead of remembering the syntax for HTML form elements, you
just make a series of perl function calls. An important fringe benefit
of this is that the value of the previous query is used to initialize
the form, so that the state of the form is preserved from invocation
to invocation.
