+		It is:
+		a tool to generate lexical analyzers. A lexical analyzer is a program
+		that transforms a stream of characters into a stream of
+		'atomic chunks of meaning', so called tokens.
+		
+		It does:
+		generate directly coded lexical analyzers, rather than table based
+		engines.
+		respond to queries on Unicode properties and regular expressions on the
+		command line.
+		generate state transition graphs of the generated engines.
