/* -----------------------------------------------------------------------------
 *
 * Example: write a STL file
 *
 * Just give the filepath and an initialized gmio_stl_mesh object to
 * gmio_stl_write_file().
 * The gmio_stl_mesh object defines the interface to access the underlying user
 * mesh.
 *
 * Note if you want to have control over the stream to be used, call
 * gmio_stl_write() instead.
