+long-description = """
+
+Ayacc is an Ada parser generator in the style of yacc(1).
+
+The first implementation was written by David Taback and Deepak Tolani
+at the University of California, Irvine.  The last version that was released
+appeared to be the Ayacc 1.1 released in 1994.
+
+Ayacc was used and improved by P2Ada, the Pascal to Ada translator.
+This version of Ayacc is derived from the P2Ada ayacc implementation
+released in August 2010.
+
+This version brings a number of improvements:
+
+- Ayacc now uses more standard options to configure the code generation
+- The parser was improved to configure the parser stack size and
+  support Ada child packages.
+- The grammar supports the %unit directive to control the Ada child packages.
+- Several options provide a better control of the generated code.
+- Ayacc can generate a reentrant parser.
