+What is g2 ? 
+============
+
+Short version (if you are in hurry): 
+
+     - 2D graphic library 
+     - Simple to use 
+     - Supports several types of output devices (currently X11, 
+       gd (PNG, JPEG), PostScript) 
+     - Concept allows easy implementation of new device types 
+     - Virtual devices allow to send output simultaneously to several devices 
+     - User definable coordinate system 
+     - Written in ANSI-C 
+     - Tested under Digital Unix, AIX, Linux, VMS and Windows NT 
+     - Fortran interface 
+
+Long version: 
+
+g2 is a simple to use graphics library for 2D graphical applications
+written in Ansi-C. This library provides a comprehensive set of
+functions for simultaneous generation of graphical output on different
+types of devices. Presently, following devices are currently supported
+by g2: X11, gd (PNG, JPEG), PostScript (xfig and Win32 are in developement).
+One major feature of the g2_library is the concept of virtual devices. An
+arbitrary number of physical devices (such as PNG, or X11) can be
+grouped to create a so-called virtual device. Commands sent to such a
+virtual devices will automatically issued to all attached physical
+devices. This allows for example simultaneous output to a PNG file and
+a Postscript file. A virtual device in turn can be attached to another
+virtual device, allowing to construct trees of devices.  Virtual
+devices can also be useful when using different user-coordinate
+systems. E.g. one X11 window showing an overview of a graphical
+output, and a second window showing a zoom of a more detailed area of
+the graphic. Drawing in both windows is performed by one single
+command to the virtual device.
+

+                                   /-------> PNG:   g2_attach(id_PNG,... 
+            ----------------------- 
+g2_plot---> | Virtual device: id |--------> X11:   g2_attach(id_X11,...
+            -----------------------
+                                   \-------> PS:    g2_attach(id_PS,...
+
+If you don't need or like the concept of virtual devices, simply ignore it.
