+Description: this is quick and dirty patch to use %parse-param instead
+ of deprecated YYPARSE_PARAM (and eventually removed in Bison 3.0).
+ %parse-param was added in bison 1.875, over a decade ago, so no
+ Build-Depends adjustments are needed. :-)

+		Maude is a high-performance reflective language and system supporting
+		both equational and rewriting logic specification and programming for a
+		wide range of applications. Maude has been influenced in important ways
+		by the OBJ3 language, which can be regarded as an equational logic
+		sublanguage. Besides supporting equational specification and
+		programming, Maude also supports rewriting logic computation.
