=head1 METHODS IN CGI.pm NOT IN CGI::Simple

Here is a complete list of what is not included in CGI::Simple. Basically all
the HTML related stuff plus large redundant chunks of the guts. The check.pl
script in the /misc dir will check to see if a script is using any of these.

=head2 Guts - rearranged, recoded, renamed and hacked out of existence

    initialize_globals()
    compile()
    expand_tags()
    self_or_default()
    self_or_CGI()
    init()
    to_filehandle()
    save_request()
    parse_params()
    add_parameter()
    binmode()
    _make_tag_func()
    AUTOLOAD()
    _compile()
    _setup_symbols()
    new_MultipartBuffer()
    read_from_client()

=head2 Upload Related

CGI::Simple uses anonymous tempfiles supplied by IO::File to spool uploaded
files to.

    private_tempfiles() # automatic in CGI::Simple
    tmpFileName()       # all upload files are anonymous
    uploadInfo()        # relied on FH access, replaced with upload_info()


=head2 Really Private Subs (marked as so)

    previous_or_default()
    register_parameter()
    get_fields()
    _set_values_and_labels()
    _compile_all()
    asString()
    compare()

=head2 Internal Multipart Parsing Routines

    read_multipart()
    readHeader()
    readBody()
