-v var1[,...]

Compare SD data on variable(s) var1 ,... only

-u var1[,...]

Compare vdata on variable(s) var1 ,... only

-e count

Print difference up to count number for each variable

-t limit

-p relative

Print difference when it is greater than a relative limit

	file1		File name of the first HDF file
