+    longDescription = ''
+      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.
