-DESCRIPTION="bison - A yacc-compatible parser generator" 
+SUMMARY="A yacc-compatible parser generator" 
+DESCRIPTION="Bison is a general-purpose parser generator that converts an annotated 
+	context-free grammar into an LALR(1) or GLR parser for that grammar. Once you 
+	are proficient with Bison, you can use it to develop a wide range of language 
+	parsers, from those used in simple desk calculators to complex programming 
+	languages.
+
+	Bison is upward compatible with Yacc: all properly-written Yacc grammars ought 
+	to work with Bison with no change. Anyone familiar with Yacc should be able to 
+	use Bison with little trouble. You need to be fluent in C or C++ programming in
+	order to use Bison."
