=head1 DESCRIPTION
-Provides a convinient way of setting up an CGI enviroment from a HTTP::Request.
+Provides a convenient way of setting up an CGI environment from an HTTP::Request.
=head1 METHODS
=item new ( $request [, key => value ] )
-Contructor, first argument must be a instance of HTTP::Request
-followed by optional pairs of environment key and value.
+Constructor. The first argument must be a instance of HTTP::Request, followed
+by optional pairs of environment key and value.
-=item enviroment
+=item environment
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 rawhandles
-
-Don't redefine STDIN/STDOUT/STDERR internally.
+Sets up the environment and descriptors.
=item restore
-Restores the enviroment and descriptors. Can only be called after setup.
+Restores the environment and descriptors. Can only be called after setup.
