    This is the Gmsh FAQ
    
    ********************************************************************
    
    Section 1: The basics
    
    * 1.1 What is Gmsh?
    
    Gmsh is an automatic three-dimensional finite element mesh generator
    with built-in pre- and post-processing facilities. Its design goal is
    to provide a simple meshing tool for academic problems with parametric
    input and advanced visualization capabilities.
    
    * 1.2 What are the terms and conditions of use?
    
    Gmsh is distributed under the terms of the GNU General Public
    License. See the file 'doc/LICENSE' for more information, or go to the
    GNU foundation's web site at http://www.gnu.org.
    
    * 1.3 What does 'Gmsh' mean?
    
    Nothing ;-)
    
    (Note that in the US, people tend to pronounce 'Gmsh' as
    'Gee-mesh'. Yeehaa!)
    
    * 1.4 Where can I find more information?
    
    http://www.geuz.org/gmsh/ is the primary location to obtain
    information about Gmsh. You will for example find a complete reference
    manual as well as a searchable archive of the Gmsh mailing list
    (gmsh@geuz.org) on this webpage.
    
    ********************************************************************
    
    Section 2: Installation
    
    * 2.1 Which OSes does Gmsh run on?
    
    Gmsh is known to run on Windows 95/98/NT/2000/XP, Linux, Mac OS X,
    Compaq Tru64 Unix (aka OSF1, aka Digital Unix), Sun OS, IBM AIX, SGI
    IRIX, FreeBSD and HP-UX. It should compile on any Unix-like operating
    system, provided that you have access to a recent C and C++ compiler.
    
    * 2.2 Are there additional requirements to run Gmsh?
    
    You should have the OpenGL libraries installed on your system, and in
    the path of the library loader. A free replacement for OpenGL can be
    found at http://www.mesa3d.org.
    
    * 2.3 What do I need to compile Gmsh from the sources?
    
    You need a C and a C++ compiler (e.g. the GNU compilers gcc and g++)
    as well as the GSL (version 1.2 or higher; freely available from
    http://sources.redhat.com/gsl/) and FLTK (version 1.1.x, configured
    with OpenGL support; freely available from http://www.fltk.org).
    
    * 2.4 How do I compile Gmsh?
    
    Just type './configure; make; make install'. If you change some
    configuration options (type './configure --help' to get the list of
    all available choices), don't forget to do 'make clean' before
    rebuilding Gmsh.
