## How to compile and run the program
 1. Set following variables in Makefile to the correct path in your system
        XHOME :      include path (location of) motif/lesstif 
        OGL_INCDIR : include path for openGL
        OGL_LIBDIR : library path for openGL
        CGAL_INCDIR : include path for CGAL
        CGAL_LIBDIR : library path for CGAL
        BLITZ_INCDIR : include path for Blitz
        BLITZ_LIBDIR : library path for Blitz
    You can obtain the libraries from following web sites,  
        Mesa (3.2): http://mesa3d.sourceforge.net/
        CGAL (2.0 or 2.1): http://www.cs.uu.nl/CGAL/
        Blitz (0.5beta3): http://oonumerics.org/blitz/
 2.  ./make
 3.  cd bin; ./pccm ../mesh/quint.mesh 
                     (or some other file in the directory mesh)
 4.  To rotate, scale and move the object
     use mouse, mouse+ctrl and mouse+shift

--------------------- experience:
With blitz and  GL and lesstif in place I only had to download 
CGAL to my home directory and change to
    CGAL_INCDIR = /home/jorg/CGAL-2.1/include
    CGAL_LIBDIR = /home/jorg/CGAL-2.1/lib/i686_Linux-2.2.5-15_g++-egcs-2.91.66

on error:
    CGAL/config.h:78: CGAL/compiler_config.h: No such file or directory
I added
    ln -s config/i686_Linux-2.2.5-15_g++-egcs-2.91.66/CGAL/compiler_config.h compiler_config.h

on error
    -libXm.so.2 not found
I added in the csh
    setenv LD_LIBRARY_PATH /home/jorg/CGAL-2.1/lib/i686_Linux-2.2.5-15_g++-egcs-2.91.66:/usr/local/lib:/usr/X11R6/lib:/usr/lib
