+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.
+
+Necessary libs:
+
+OpenGL
+GLU
+GLUI User Interface Library
+GLUT (freeglut)
+libxml++
+glibmm
+
+
+
+USAGE
+-----
+
+Keys:
+
+Esc quit
++ zoom in
+- zoom out
+y rotate around the y-axis
+Up move camera up
+Down move camera down
+Left move camera left
+Right move camera right
+PageUp move camera forth
+PageDown move camera back
+
+
+Rules:
+
+= name/rule separator
+A-Z rewrite operator, step forward
++ turn left
+- turn right
+& pitch down
+^ pitch up
+\ roll left
+/ roll right
+| turn around 180 degrees
+[ save state to stack
+] restore state from stack
+{ first vertex of a filled surface
+} last vertex of a filled surface
+f one vertex of a filled surface
+! decrement diameter of segment
+
+
+Example:
+
+The GUI input
+
+Axiom: A
+Rule #1: A=A/[!+A&A]/A
+Angle: 30.0
+Iterations: 4
+
+will render a simple l-system and create the xml-structure
+
+<?xml version="1.0"?>
+<lsystem>
+ <axiom>A</axiom>
+ <rule name="A">A/[!+A&A]/A</rule>
+ <angle>30.0</angle>
+ <iterations>4</iterations>
+</lsystem>
+
+and save it to the file named "lsystem.xml" when quitting. The same file will
+be initially loaded every time LSystem3d is started.
