How do you determine if a HTML file contains new servers
or urls?

Well, the tool:

	http://anarky.stsci.edu/astroweb/findnewurl

is a Tcl script 

# usage: findnewurls ref.html new1.html ...
# 
#	ref.html =  File of known URL's
#	new*.html = File of possible URL's

which writes HTML to STDOUT containing any URLs
found in new*.html.

I wrote to see if Lycos and other folks have new
URLs.

It can get fooled by equivalent hostnames, e.g.,

	www.stsci.edu == marvel.stsci.edu
