There is also a question of just what constitutes a "version" I am saying this 
because the proposed windows solution to this suggested a tool that 
increments the version number every time I initiate a new _build command_, 
completely irrespective of whether changes occurred between successive 
compilations or not. I view that as completely unworkable.
