+Usage: h5watch [OPTIONS] [OBJECT]
+
+     OPTIONS
+        --help            Print a usage message and exit.
+        --version         Print version number and exit.
+        --label           Label members of compound typed dataset.
+        --simple          Use a machine-readable output format.
+        --dim             Monitor changes in size of dataset dimensions only.
+        --width=N         Set the number of columns to N for output.
+                              A value of 0 sets the number of columns to the
+                              maximum (65535). The default width is 80 columns.
+        --polling=N       Set the polling interval to N (in seconds) when the
+                              dataset will be checked for appended data.  The default
+                              polling interval is 1.
+        --fields=<list_of_fields>
+                              Display data for the fields specified in <list_of_fields>
+                              for a compound data type.  <list_of_fields> can be
+                              specified as follows:
+                                   1) A comma-separated list of field names in a
+                                   compound data type.  "," is the separator
+                                   for field names while "." is the separator
+                                   for a nested field.
+                                   2) A single field name in a compound data type.
+                                   Can use this option multiple times.
+                              Note that backslash is the escape character to avoid
+                              characters in field names that conflict with the tool's
+                              separators.
+
+     OBJECT is specified as [<filename>/<path_to_dataset>/<dsetname>]
+        <filename>            Name of the HDF5 file.  It may be preceded by path
+                              separated by slashes to the specified HDF5 file.
+        <path_to_dataset>     Path separated by slashes to the specified dataset
+        <dsetname>            Name of the dataset
+
+     User can end the h5watch process by ctrl-C (SIGINT) or kill the process (SIGTERM).
