Update of /home/or/cvsroot/tor/doc
In directory moria.mit.edu:/tmp/cvs-serv8152/doc

Modified Files:
	tor-spec.txt 
Log Message:
Remove support for looking at old directory/routerdesc elements; mark non-new elements optional; switch to new format for dir-signing-key; start accepting newer elements so we can mark them as non-opt later; make tor-spec say the right stuff.
