Description: 	`libparsing` is a parsing element grammar (PEG) library written in C with
        	Python bindings. It offers a fairly good performance while allowing for a
        	lot of flexibility. It mainly intended to be used to create programming
        	languages and software engineering tools.
        
        	As opposed to more traditional parsing techniques, the grammar is not compiled
        	but constructed using an API that allows dynamic update of the grammar.
        
        	The parser does not do any tokeninzation, the instead input stream is
        	consumed and parsing elements are dynamically asked to match the next
        	element of it. Once parsing elements match, the resulting matched input is
        	processed and an action is triggered.
        
        	Parsing elements support:
        
        	- backtracking, ie. going back in the input stream if a match is not found
        	- cherry-picking, ie. skipping unrecognized input
        	- contextual rules, ie. a rule that will match or not depending on external
        	  variables
        	 - dynamic grammar update, where you can change the grammar on the fly
        
        	Parsing elements are usually slower than compiled or FSM-based parsers as
        	they trade performance for flexibility. It's probably not a great idea to
        	use them if parsing has to happen as fast as possible (ie. a protocol
        	implementation), but it is a great use for programming languages, as it
        	opens up the door to dynamic syntax plug-ins and multiple language
        	embedding.
        
        	If you're interested in PEG, you can start reading Brian Ford's original
        	article. Projects such as PEG/LEG by Ian Piumarta <http://piumarta.com/software/peg/>
        	,OMeta by Alessandro Warth <http://www.tinlizzie.org/ometa/>
        	or Haskell's Parsec library <https://www.haskell.org/haskellwiki/Parsec>
        	are of particular interest in the field.
