DESCRIPTION
-----------

LSystem3d is a experimental Lindenmayer System generator with 3d capabilities,
whose main goal is to generate all kinds of plants or whatever fractal
L-system structures the user desires. For now, LSystem3D is highly under
development and is considered alpha, that is, lots of things are missing and
it will probably not work 100% accurate.



REQUIREMENTS
------------

Currently tested in Debian GNU/Linux (Sid) only, but should compile fine on
other platforms without bigger modification.

A fast computer with HW accelerated 3D would be nice.

Dependencies;

OpenGL
FOX toolkit
libxml++
glibmm
