Compiling
=========
To compile this project you need Qt4.4 or later, only the qt-core library is used.

To generate a makefile call the 'qmake' command in the vng directory.  Make
sure you call the one from the right Qt release.
Some linux distros ship this command names 'qmake-qt4'

After calling qmake, compile the project like you would any other.  This is
platform dependent and could be "nmake", "make" etc.

You will find the "vng" command line in the build directory, on Windows it will
be in a subdirectory like debug\vng.exe or release\vng.exe.

Thats all!
