+ Note)  file1 and file2 can be the same file. Use
+
+    h5diff file1 file1 /g1/dset1 /g1/dset2
+
+    to compare '/g1/dset1' and '/g1/dset2' in the same file
+
+ If no objects [obj1[obj2]] are specified, h5diff only compares objects
+   with the same absolute path in both files. The compare criteria is:
+   1) datasets: numerical array differences 2) groups: name string difference
+   3) datatypes: the return value of H5Tequal 2) links: name string difference
+   of the linked value
