class cgi :cgi_environment -> output_type -> request_method -> cgi_argument list ->object..end
cgi env op meth args constructs Netcgi.cgi objects. The
environment #out_channel is wrapped into a transactional channel
or a discarding channel according to op (`Direct or
`Transactional) and request_method (`HEAD requests must only
return a header). For standard cases, when POST and PUT arguments
are available through a Netchannels.in_obj_channel, we recommend
you use Netcgi_common.cgi_with_args that will parse the
arguments for you and check preconditions.
Remark: You may think that the argument meth is superfluous as
it can be deduced from env#cgi_request_method. While it is true
for `DELETE, `GET, `HEAD and `POST, the `PUT takes a
Netcgi_common.cgi_argument parameter. Setting correctly this
parameter and decoding env#cgi_request_method is done for you by
Netcgi_common.cgi_with_args.
