-h5diff has four modes of output:
- Normal mode: print the number of differences found and where they occured
- Report mode: print the above plus the differences
- Verbose mode: print the above plus a list of objects and warnings
- Quiet mode: do not print output (h5diff always returns an exit code of 1 when differences are found)

-1) h5diff file1 file2 /g1/dset1 /g1/dset2
+ Return exit code:
 
-   Compares object '/g1/dset1' in file1 with '/g1/dset2' in file2
+  1 if differences found, 0 if no differences, -1 if error
 
-2) h5diff file1 file2 /g1/dset1

-If no objects 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
