  	<li>proxy coordinates (targeted for v0.2):
  	create a coordinate for a non-overlay node.</li>
+ 	<li>add application-level coordinates for improved stability
  	</ul>
  
+ 	<p><b>Logging and Log Files</b>
+ 
+ 	<p>
+ 	Logging levels for particular classes and subtrees can be set
+ 	in the <i>config/log.config</i> file.<BR>
+ 	E.g. <tt>edu.harvard.syrah.pyxida.level = DEBUG</tt>
+ 
+ 
+ 	Setting this to DEBUG will produce a lot of output.  We
+ 	suggest INFO, which will produce a periodic summary.
+ 
+ 	<p>
+ 	The basic format of the logs is:<BR>
+ 	<code>DEBUG/INFO/WARNING/ERROR timestamp java-class : message</code><BR>
+ 	e.g. <code>DE 1165381552727 NCManager         : setting timer to 9477</code><BR>
+ 
+ 	<p>
+ 	Each network coordinate summarizes its behavior with lines of
+ 	the form:<BR>
+ 
+ 	<code>
+ 	update: [sc=[11.498,-69.529,14.73,16.269,h19.323],<BR>
+ 	ac=[6.827,-41.283,8.746,9.66,h11.473],<BR>
+ 	er=0.675,sys_re50=0.454,sys_re95=1,app_re50=0.672,app_re95=1.93,<BR>
+ 	sys_dd=1.256,app_dd=5.455,ne=2.025,rd=0,<BR>
+ 	sf=5205.779,af=5205.779,rrl=0.278,narl=0.212,ralp=0.338,<BR>
+ 	age=3,vl=72,gr=0.007,nn=96.6]
+ 	</code>
+ 
+ 	<p>
+ 	The format of these update lines is:<BR>
+ 	sc: system-level coordinate<BR>
+ 	ac: app-level coordinate (see our ICDCS/WORLDS papers about this)<BR>
+ 	er: Vivaldi error/confidence (an EWMA)<BR>
+ 	sys_re50 = median (50th pctl) of the distribution of relative errors for the recent past<BR>
+ 	sys_re95 = 95th pctl of this distribution<BR>
+ 	app_* = same but for app-level coordinate (however, they are not fully functional in our current version)<BR>
+ 	sys_dd = sys-level coordinate change per update (distance delta)<BR>
+ 	sf = avg number of milliseconds between updates<BR>
+ 	nn = distance to nearest neighbor<BR>
+ 	rrl = Lua's relative rank loss<BR>
+ 	narl and ralp are two metrics from our ICDCS and WORLDS papers<BR>
+ 	gr = the pull of gravity<BR> 
+ 
+ 	<p>
+ 	Typically the place to start is <code>sys_re50</code>.
+ 	On the Internet, the median of the distribution of these
+ 	values should range between 8-20% depending on the particular
+ 	set of machines you are using.
