+
+A utility that reads an RDF file, builds a model, sorts all of the URIs that have
+labels, and produces a file of those labels, one per line. The idea is that this 
+file could be translated, and the result could be put into RDF by label_inserter.rb
+
+This required the RDF.rb gem: sudo gem install rdf
+
+On the command line provide the path to the RDF file. E.g.:
+
+	label_stripper.rb '../../vivo-core-1.5-annotations.rdf'
+
