-These classes, present in earlier versions of the :mod:`cgi` module, are still

-:class:`FieldStorage` class.

-:class:`SvFormContentDict` stores single value form content as dictionary; it

-:class:`FormContentDict` stores multiple value form content as a dictionary (the
-form items are lists of values).  Useful if your form contains multiple fields

-Other classes (:class:`FormContent`, :class:`InterpFormContentDict`) are present

-these and would be inconvenienced when they disappeared from a next version of
-this module, drop me a note.
