	  		Drawterm is a Unix and Windows program that simulates
	  		a Plan 9 terminal to connect to a Plan 9 cpu server.
	- 		The version in this directory speaks the pre-9P2000 
	- 		protocols.  
	  
	- 		A new 9P2000 version is in progress but still crashes
	- 		with some regularity on Unix.  It can be found at
	- 		  http://cvs.pdos.csail.mit.edu/cvs/drawterm/
	- 		or use
	- 		  cvs -d :pserver:[email protected]:/cvs co drawterm
	- 		For more information about CVS, see
	- 		  http://swtch.com/plan9port/man/man1/cvs.html
	+ 		See drawterm/README for details.
	  
	  	u9fs/
	  		U9fs is a simple 9P server that runs on Unix.
