DESCRIPTION

       This module is a wrapper for the completely object oriented CGI::Simple module and
       provides a simple functional style interface. It provides two different methods to import
       function names into your namespace.

   Autoloading
       If you specify the '-autoload' pragma like this:

           use CGI::Simple::Standard qw( -autoload );

       Then it will use AUTOLOAD and a symbol table trick to export only those subs you actually
       call into your namespace. When you specify the '-autoload' pragma this module exports a
       single AUTOLOAD subroutine into you namespace. This will clash with any AUTOLOAD sub that
       exists in the calling namespace so if you are using AUTOLOAD for something else don't use
       this pragma.

       Anyway, when you call a subroutine that is not defined in your script this AUTOLOAD sub
       will be called. The first time this happens it will initialize a CGI::Simple object and
       then apply the requested method (if it exists) to it. A fatal exception will be thrown if
       you try to use an undefined method (function).

   Specified Export
       Alternatively you can specify the functions you wish to import. You can do this on a per
       function basis like this:

           use CGI::Simple::Standard qw( param upload query_string Dump );

       or utilize the %EXPORT_TAGS that group functions into related groups.  Here are the
       groupings:

         %EXPORT_TAGS = (
           ':html'     => [ qw(:misc) ],
           ':standard' => [ qw(:core :access) ],
           ':cgi'      => [ qw(:core :access) ],
           ':all'      => [ qw(:core :misc :cookie :header :push :debug :cgi-lib
                               :access :internal) ],
           ':core'     => [ qw(param add_param param_fetch url_param keywords
                               append Delete delete_all Delete_all upload
                               query_string parse_query_string  parse_keywordlist
                               Vars save_parameters restore_parameters) ],
           ':misc'     => [ qw(url_decode url_encode escapeHTML unescapeHTML put) ],
           ':cookie'   => [ qw(cookie raw_cookie) ],
           ':header'   => [ qw(header cache no_cache redirect) ],
           ':push'     => [ qw(multipart_init multipart_start multipart_end
                               multipart_final) ],
           ':debug'    => [ qw(Dump as_string cgi_error _cgi_object) ],
           ':cgi-lib'  => [ qw(ReadParse SplitParam MethGet MethPost MyBaseUrl MyURL
                               MyFullUrl PrintHeader HtmlTop HtmlBot PrintVariables
                               PrintEnv CgiDie CgiError Vars) ],
           ':ssl'      => [ qw(https) ],
           ':access'   => [ qw(version nph all_parameters charset crlf globals
                               auth_type content_length content_type document_root
                               gateway_interface path_translated referer remote_addr
                               remote_host remote_ident remote_user request_method
                               script_name server_name server_port server_protocol
                               server_software user_name user_agent virtual_host
                               path_info Accept http https protocol url self_url
                               state) ],
           ':internal' => [ qw(_initialize_globals _use_cgi_pm_global_settings
                               _store_globals _reset_globals) ]
           );

       The familiar CGI.pm tags are available but do not include the HTML functionality. You
       specify the import of some function groups like this:

       use CGI::Simple::Standard qw( :core :cookie :header );

       Note that the function groups all start with a : char.

   Mix and Match
       You can use the '-autoload' pragma, specifically named function imports and tag group
       imports together if you desire.

$POST_MAX and $DISABLE_UPLOADS

       If you wish to set $POST_MAX or $DISABLE_UPLOADS you must do this *after* the use
       statement and *before* the first function call as shown in the synopsis.

       Unlike CGI.pm uploads are disabled by default and the maximum acceptable data via post is
       capped at 102_400kB rather than infinity. This is specifically to avoid denial of service
       attacks by default. To enable uploads and to allow them to be of infinite size you simply:

           $CGI::Simple::Standard::POST_MAX = -1;         # infinite size upload
           $CGI::Simple::Standard::$DISABLE_UPLOADS = 0;  # enable uploads

       Alternatively you can specify the CGI.pm default values as shown above by specifying the
       '-default' pragma in your use statement.

           use CGI::Simple::Standard qw( -default ..... );

EXPORT

       Nothing by default.

       Under the '-autoload' pragma the AUTOLOAD subroutine is exported into the calling
       namespace. Additional subroutines are only imported into this namespace if you physically
       call them. They are installed in the symbol table the first time you use them to save
       repeated calls to AUTOLOAD.

       If you specifically request a function or group of functions via an EXPORT_TAG then stubs
       of these functions are exported into the calling namespace. These stub functions will be
       replaced with the real functions only if you actually call them saving wasted compilation
       effort.

FUNCTION DETAILS

       This is a wrapper module for CGI::Simple. Virtually all the methods available in the OO
       interface are available via the functional interface. Several method names are aliased to
       prevent namespace conflicts:

           $q->delete('foo')   =>  Delete('foo')
           $q->delete_all      =>  Delete_all() or delete_all()
           $q->save(\*FH)      =>  save_parameters(\*FH)
           $q->accept()        =>  Accept()

       Although you could use the new() function to genrate new OO CGI::Simple objects the
       restore_parameters() function is a better choice as it operates like new but on the
       correct underlying CGI::Simple object for the functional interface.

       restore_parameters() can be used exactly as you might use new() in that you can supply
       arguments to it such as query strings, hashes and file handles to re-initialize your
       underlying object.

           $q->new CGI::Simple()                => restore_parameters()
           $q->new CGI::Simple({foo=>'bar'})    => restore_parameters({foo=>'bar'})
           $q->new CGI::Simple($query_string)   => restore_parameters($query_string)
           $q->new CGI::Simple(\*FH)            => restore_parameters(\*FH)

       For full details of the available functions see the CGI::Simple docs. Just remove the $q->
       part and use the method name directly.

BUGS

       As this is 0.01 there are almost bound to be some.
