-usage: h5diff [OPTIONS] file1 file2 [obj1[obj2]] 
-  file1                    File name of the first HDF5 file
-  file2                    File name of the second HDF5 file
-  [obj1]                   Name of an HDF5 object, in absolute path
-  [obj2]                   Name of an HDF5 object, in absolute path
-  OPTIONS
-   -h, --help              Print a usage message and exit
-   -V, --version           Print version number and exit
-   -r, --report            Report mode. Print differences
-   -v, --verbose           Verbose mode. Print differences, list of objects
-   -q, --quiet             Quiet mode. Do not do output
-   -c, --compare           List objects that are not comparable
-   -N, --nan               Avoid NaNs detection
-   -n C, --count=C         Print differences up to C number
-   -d D, --delta=D         Print difference when greater than limit D
-   -p R, --relative=R      Print difference when greater than relative limit R
-
-  C - is a positive integer
-  D - is a positive number. Compare criteria is |a - b| > D
-  R - is a positive number. Compare criteria is |(b-a)/a| > R
-
- Modes of output:
-
-  Default mode: print the number of differences found and where they occured
-  -r Report mode: print the above plus the differences
-  -v Verbose mode: print the above plus a list of objects and warnings
-  -q Quiet mode: do not print output
-
- Compare criteria
-
- 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 4) links: name string difference
-   of the linked value
-
- Return exit code:
-
-  1 if differences found, 0 if no differences, 2 if error
-
- Examples of use:
-
- 1) h5diff file1 file2 /g1/dset1 /g1/dset2
-
-    Compares object '/g1/dset1' in file1 with '/g1/dset2' in file2
-
- 2) h5diff file1 file2 /g1/dset1
-
-    Compares object '/g1/dset1' in both files
-
- 3) h5diff file1 file2
-
-    Compares all objects in both files
-
- 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
-
+dataset: </g1/dset3> and </g1/dset4>
+6 differences found
