	* _May-2-2007._ Version 0.3 of the koala compiler has been released. Checkout HowToObtainKoalaCompiler

*Description*

The Koala-compiler package forms an Open Source implementation of Koala. It is independent of the official Koala compiler as developed by [[http://www.extra.research.philips.com/SAE/koala/][Philips Research]].
The package provides an open compiler implementation that can be used for research and for education purposes.

Koala is a component definition language used by Philips consumer
electroniccs to model components (as C modules), composition (as C
compilation and linking), and variability (as CPP macros and partial
evaluation).

The Koala component model consists of a component language, which
supports definition of:
	* interfaces (both required and provided)
	* data types
	* components
	* diversity (by means of a diversity interfaces)
	* component compositions

Component compositions consist of collections of components and wires that
connect provides and requires interfaces (see picture below).

*Contents*

The koala-compiler package includes:
	* The Koala language definition in SDF
	* A Koala parser
	* A Koala normalizer
	* A Koala pretty-printer
	* A Koala vizualization tool
	* A backend for C (+Makefile generation). This provides the functionality of the original Philips Koala compiler
	* A backend for [[http://www.cs.uu.nl/groups/ST/Merijn/PaperSourceTreeComposition][Source Tree Composition]]
