+%description -n python3-ply
+PLY is a straightforward lex/yacc implementation. Here is a list of its 
+essential features:
+* It is implemented entirely in Python.
+* It uses LR-parsing which is reasonably efficient and well suited for larger 
+  grammars.
+* PLY provides most of the standard lex/yacc features including support 
+  for empty productions, precedence rules, error recovery, and support 
+  for ambiguous grammars.
+* PLY is straightforward to use and provides very extensive error checking.
+* PLY doesn't try to do anything more or less than provide the basic lex/yacc 
+  functionality. In other words, it's not a large parsing framework or a 
+  component of some larger system.
