-pyparsing module - Classes and methods to define and execute parsing grammars
-
-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.  With pyparsing, you
-don't need to learn a new syntax for defining grammars or matching expressions - the parsing module
-provides a library of classes that you use to construct the grammar directly in Python.
-
-Here is a program to parse "Hello, World!" (or any greeting of the form "<salutation>, <addressee>!")::
-
-    from pyparsing import Word, alphas
-
-    # define grammar of a greeting
-    greet = Word( alphas ) + "," + Word( alphas ) + "!"
-
-    hello = "Hello, World!"
-    print hello, "->", greet.parseString( hello )
-
-The program outputs the following::
-
-    Hello, World! -> ['Hello', ',', 'World', '!']
-
-The Python representation of the grammar is quite readable, owing to the self-explanatory
-class names, and the use of '+', '|' and '^' operators.
-
-The parsed results returned from parseString() can be accessed as a nested list, a dictionary, or an
-object with named attributes.
-
-The pyparsing module handles some of the problems that are typically vexing when writing text parsers:
- - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello  ,  World  !", etc.)
- - quoted strings
- - embedded comments
