=head1 DESCRIPTION
+Provides a convinient way of setting up an CGI enviroment from a HTTP::Request.
+
=head1 METHODS
=over 4
-=item new
+=item new ( $request [, key => value ] )
+
+Contructor, first argument must be a instance of HTTP::Request
+followed by optional pairs of environment keys and values.
=item enviroment
+Returns a hashref containing the environment that will be used in setup.
+Changing the hashref after setup has been called will have no effect.
+
=item setup
+Setups the environment and descriptors.
+
=item restore
+Restores the enviroment and descriptors. Can only be called after setup.
+
=item request
+Returns the request given to constructor.
+
+=item response
+
+Returns a HTTP::Response. Can only be called after restore.
+
=item stdin
+Accessor for handle that will be used for STDIN, must be a real seekable
+handle with an file descriptor. Defaults to a tempoary IO::File instance.
+
=item stdout
+Accessor for handle that will be used for STDOUT, must be a real seekable
+handle with an file descriptor. Defaults to a tempoary IO::File instance.
+
=item stderr
+Accessor for handle that will be used for STDERR, must be a real seekable
+handle with an file descriptor.
