Draco Econometrics
Copyright 2006-2008 Approximatrix, LLC

Introduction
------------
Welcome to Draco, an econometrics package from Approximatrix.  Draco differs
from other offerings in two major ways: 

	1) It is free software (GPL v3)
	2) It is simple to use
	
Draco is written in pure Java, and can be run on any system supporting Java 5 or
higher, including Windows, GNU/Linux, *BSDs, Solaris, Mac OS X, and many others.

An online manual has been included with all appropriate information.

Building from Source
--------------------
Approximatrix, LLC makes several binary packages available at the website:

http://approximatrix.com/products/draco

These binary packages include Windows installer, Debian-compatible packages, and
a universal binary distribution.  If you still wish to build from source,
continue reading.

Draco ships with an Ant build script capable of building the complete system. 
Draco currently requires the following to perform a build:

	* Java 5-compatible javac compiler
	* Apache Ant 1.7 including optional tasks
	* JUnit 4 (installed in Ant classpath)
	* JavaCC compiler
    * makensis executable (for building the Windows installer)
    * rpm executable (for building the RPM GNU/Linux package)

All libraries required by Draco and all extra Ant tasks for packaging are
included in the source archive.

Before building, read the Ant manual instructions on setting up the JavaCC task,
which requires an environment variable to be set.

If all requirements are met, simply type:

	ant clean dist
	
The command above will build all distribution files in the 'build' directory.
