=item * stdin
-Filehandle to be used as C<STDIN>, defaults to a temporary file. If value is
-C<undef>, C<STDIN> will be left as is.
+A filehandle to be used as standard input, defaults to a temporary filehandle.
+If C<stdin> is C<undef>, standard input will be left as is.
stdin => IO::File->new_tmpfile
stdin => IO::String->new
=item * stdout
-Filehandle to be used as C<STDOUT>, defaults to a temporary file. If value is
-C<undef>, C<STDOUT> will be left as is.
+A filehandle to be used as standard output, defaults to a temporary filehandle.
+If C<stdout> is C<undef>, standard output will be left as is.
stdout => IO::File->new_tmpfile

=item * stderr
-Filehandle to be used as C<STDERR>, defaults to C<undef>. If value is C<undef>,
-C<STDERR> will be left as is.
+A filehandle to be used as standard error, defaults to C<undef>. If C<stderr> is
+C<undef>, standard error will be left as is.
stderr => IO::File->new_tmpfile
stderr => IO::String->new
=item * environment
+A C<HASH> of additional environment variables to be used in CGI.
+C<HTTP::Request::AsCGI> doesn't autmatically merge C<%ENV>, it has to be
+explicitly given if that is desired. Environment variables given in this
+C<HASH> isn't overridden by C<HTTP::Request::AsCGI>.

+to C<true>.
+
rewind => 0
