The things one finds

I was trying to connect to the "PIR", which is a protein database, but I
couldn't remember the URL.  Anyway, I put in "http://www.pir.org/", which
took me someplace completely different.  One of the files on that site
purports to be a detailed analysis of the Summer Institute of Linguistics
(one of my favorite online sources).  The URL of that file is
"http://www.pir.org/gw/sil.txt".  Does anybody know if it's totally
whacko or if the analysis is on the level?
