+FTGL 2.1
+5 December 2004
+
+DESCRIPTION:
+
+FTGL is a free open source library to enable developers to use arbitrary
+fonts in their OpenGL (www.opengl.org)  applications.
+Unlike other OpenGL font libraries FTGL uses standard font file formats
+so doesn't need a preprocessing step to convert the high quality font data
+into a lesser quality, proprietary format.
+FTGL uses the Freetype (www.freetype.org) font library to open and 'decode'
+the fonts. It then takes that output and stores it in a format most efficient
+for OpenGL rendering.
+
+Rendering modes supported are
+- Bit maps
+- Antialiased Pix maps
+- Texture maps
+- Outlines
+- Polygon meshes
+- Extruded polygon meshes
+
+FTGL is designed to be used in commercial quality software. It has been
+written with performance, robustness and simplicity in mind.
+
+USAGE:
+
+	FTGLPixmapFont font( "Fonts:Arial");
+
+	font.FaceSize( 72);
+	
+	font.render( "Hello World!");
+
+This library was inspired by gltt, Copyright (C) 1998-1999 Stephane Rehel
+(http://gltt.sourceforge.net)
+Bezier curve code contributed by Jed Soane.
+Demo, Linux port, extrusion code and gltt maintainance by Gerard Lanois.
+Linux port by Matthias Kretz.
+Windows port by Andrew Ellerton & Max Rheiner.
+Bug fixes by Robert Osfield, Marcelo E. Magallon, Markku Rontu, Mark A. Fox,
+Patrick Rogers, Kai Huettemann.
+Containers and optimisations by Sebastien Barre.
+Autoconf Marcelo E. Magallon.
+Pixmap font modifications by Robert Bell.

+ * Caveats:
