+	look through HTMLized man pages
+	convert references like man(1) into HTML links
+
+	somewhat quick & dirty code
+	various dubious assumptions made:
+
+	[a-zA-Z0-9\-_\.]* defines legal characters in name
+	pagename(x) corresponds to pagename.x.html
+	(Fine *if* it's been converted by my scripts)
+	x in the above must be a single digit
+	(or we ignore it, which does no damage)
+	Lazy parsing: malloc() enough RAM to read in whole file
+	Limited syntax: exactly one input file, results to stdout
