 ExCSS (Pronoundec Excess) is a CSS 2.1 and CSS 3 parser for .NET.
 
 The goal of ExCSS is to make it easy to read and parse stylesheets into a friendly object model with full LINQ support.

+Version 2 has been rewritten from the ground up!  Unlike v1 which used Coco/r to generate a lexer and parser, version 2 is
 written entirely by hand.  This gives the new parser an incredibly fine grained level of detail when parsing some of the more
 unusual edge cases for CSS 3 selectors.

+ExCSS uses a Lexer and a Parser based on a CSS3-specific grammar.  The Lexer and Parser read CSS text and parse each
+character as individual tokens run against a complex set of rules that define what CSS segment each token represents.
 Once parsed, the input styles sheet is turned into a standard .NET object model.  That means it's
 fully queryable using Linq to objects.
