Plack::Middleware::ContentLength - Adds Content-Length header automatically

       Tatsuhiko Miyagawa

       Plack::Middleware::ContentLength is a middleware that automatically adds "Content-Length" header when
       it's appropriate i.e. the response has a content body with calculable size (array of chunks or a real
       filehandle).

       This middleware can also be used as a library from PSGI server implementations to automatically set
       "Content-Length" rather than in the end user level.
