 The lz77-kit is aimed at being another tool in the web-mans tool belt, enabling
 a simple and very pragmatic compression utility for various languages. It's
 perhaps not the sharpest compression-knife for heavy-duty cutting, but may
 suite some craft(wo)mens needs.
 
 This could be a simple way for you to throttle down on some of that bandwidth
 usage, at least a few bytes or so. And a byte saved is a byte earned!
 
 Features LZ77 implementations for the following languages:
 
 	- JavaScript
 	- PHP
 	- Python
 	- Java
 	- Ruby
	- Erlang
 	
 	[A language missing? Please add it to the project.] 

 USAGE
 
 	1. Get the project source code
 	2. Go to the project directory
 	3. Test and build using Ant on the comand line:
 	      
 	      shell$> ant      Tests and builds all
 	      
 	      shell$> ant -p   Shows some project information
 	      
 	4. Look in the ./output folder for built artifacts
 	5. Copy/paste what you need, but keep the license and credits please
 	
 DEPENDENCIES
 
 	- Ant (tested with 1.7.x)
 	- PHP 5.x
 	- Java 1.5
 	- Python (tested with 2.6)
	- Erlang (tested with R14B)
 	
 	- And a shell, with slashes "the right way" (/)

 DEVELOPMENT

 All source code have unit tests and the project is pretty independent and
 should be easy for any developer, with a decent development environment, to 
 check out and and start working with.
 
 Guidelines:
 
 	- Try to keep the self-dependent structure, add libs and depends into
 	  the project but be _very_ sparse.
 	  
 	- Write tests and wire them to work with the Ant buildfile.
 	
 	- Keep implementations simple and open to copy/paste (e.g. no packages or
 	  namespaces if possible).
 	  
 	- Code with joy, not in anger!

 With the hope of being of use to someone out there.
