HDF-EOS2 grid dimensional scales almost conform to CF convention.

For 1-d dimscales, described in 5.1 of CF convention document,
  * "lon" and "lat" are both dimensions and variables

For 2-d dimscales, described in 5.2 of CF convention document,
  * "lon" and "lat" are variables, but not dimensions
  * "XDim" and "YDim" are dimensions, but not variables

The fact that "XDim" and "YDim" are not variables may violate CF convention. However, we didn't want to pretend "XDim" and "YDim" have meaningful values. Previously, however, they had contained some information which is part of "lon" and "lat" respectively.

Additionally, it explicitly checks whether or not the given file has HDF-EOS2 grid, swath or point data when -eos option is given. Also, if this file contain POINT data, it terminates gracefully because we don't handle POINT, yet.
