   6 Object Graphics Library (
\ogl) is a C++ library supporting the creation and
 
   7 manipulation of simple and complex graphic images on a canvas.
 
   9 It can be found in the directory 
{\tt utils/ogl/src
} in the
 
  10 wxWindows distribution. The file 
{\tt ogl.h
} must be included to make use
 
  13 Please see 
\helpref{OGL overview
}{ogloverview
} for a general description how the object library works. For details,
 
  14 please see the 
\helpref{class reference
