Include tar files for installing on Mac or Win (Windows) machines as well as the 'std' that should eventually work on all and now works on linux machines. 'Win' omits only a routine to list attributes of a variable in a netCDF file; 'Mac' omits some routines for use with ggplot2, an advanced plotting routine, but that will still be available, just not some of the helper routines and my standard theme for defining how plots appear.
