-# sexpParser.py

-#

-# Demonstration of the pyparsing module, implementing a simple S-expression

-# parser.

-#

-# Updates:

-#  November, 2011 - fixed errors in precedence of alternatives in simpleString;

-#      fixed exception raised in verifyLen to properly signal the input string 

-#      and exception location so that markInputline works correctly; fixed 

-#      definition of decimal to accept a single '0' and optional leading '-'

-#      sign; updated tests to improve parser coverage
