	  as a second argument;
	- added ngxe_reader_timeout, ngxe_writer_timeout;

	- START argument in both reader and writer is changed to FLAGS;
	  NGXE_START is a flag for automatic start;
	- reader and writer are more smart now and can start and stop
	  depending on the write buffer;
	- added dual calls to stop and start reader and writer in 
	  a single perl -> xsub call but might not be needed anymore;
	- a few automated tests for basic functionality;
	- bugfix: failed connect to localhost was crashing, required 
	  peer->name to log an error, which was not used at all;
	- fix: ngxe_server was not returning an error if port was already
	  taken;

	- added $_[4] to the reader's callback to control the amount of
	  data to be read, might be useful for a lot of protocols and
	  very benefitial for performance;
	- added a few examples showing how to do more complex things:
	  keepalive-client, resolver;
	- added Nginx::Engine::Cookies to implement some common things
	  on top of the Nginx::Engine;
	- added Nginx::Engine::Cookies::Resolver as a ready to use
	  implementation of a simple tcp resolver on top of Net::DNS;
	- removed nginx.pm and a few other files from nginx distribution
	  to prevent from showing up on CPAN;
	- fixed: was failing to build on Mac OS X, thanks to 
	  Tatsuhiko Miyagawa;
	Internals:
	- making sure not to reschedule just stopped callback by checking
	  c->read->handler and c->write->handler;
	- bugfix: ngxe_client needed read handler as well as write handler 
	  to avoid crashing on connect to closed port on some systems;
	- calling ngx_handle_read_event() after each callback 
	  in the reader to make sure that the c->read->ready is set;
	- dummy handlers on newly accepted connection;
	- call back on ev->error in client's handler;
	- reader and writer start with a dummy handlers for itself 
	  and only use real ones with NGXE_START flag set
	- timer resets every time *_start is called;
