+SUMMARY="A python parsing module"
+DESCRIPTION="The pyparsing module is an alternative approach to creating and \
+executing simple grammars, vs. the traditional lex/yacc approach, or the \
+use of regular expressions. The pyparsing module provides a library of \
+classes that client code uses to construct the grammar directly in \
+Python code."
