Hi Paul Martz,

The example in the middle of page 37, above the one Cliff cited, looks
like it won't compile.  Did you really mean to return *grp?  I know it's
meant to show bad programming practice but the book reads like it should
compile.

osg::Group* CreateGroup()
{
   osg::ref_ptr<osg::Group> grp = new osg::Group;
   return *grp;
}
