       -D     Compare Vdata data only

       -S     Print statistics

       -vvar1[,...]
              Compare SD data on variable(s) var1,...  only

       -uvar1[,...]
              Compare vdata on variable(s) var1,... only

       -ecount
              Print difference up to count number for each variable

       -tlimit
              Print difference when it is greater than limit

       -prelative
              Print difference when it is greater than a relative limit

       file1  File name of the first HDF file

       file2  File name of the second HDF file

       The 'count' value must be a positive integer

       The 'limit' and 'relative' values must be positive numbers

       The -t compare criteria is |a - b| > limit

       The -p compare criteria is |(b-a)/a| > relative
