+versioninfo
+===========
+
+Description
+-----------
+
+Prints current version information for the CMF Processor tool and CMF file format version.
+
+The version information is printed to stdout as a JSON object.
+
+Syntax
+------
+
+.. code-block:: bash
+
+   cmfprocessor versioninfo
+
+
+Output Format
+-------------
+
+The output is a string representation of a JSON object:
+
+.. code-block:: text
+
+   {
+       "cmfprocessor": cmprocessor_version,
+       "format": cmf_format_version
+   }
+
+Note that `cmprocessor_version` is a string, but `cmf_format_version` is a number.
+
+Examples
+--------
+
+Compute hash of an FBX file:
+
+.. code-block:: bash
+
+   cmfprocessor versioninfo
+
+
+Compute hash in a script (PowerShell):
+
+.. code-block:: powershell
+
+   $versioninfo = cmfprocessor versioninfo
+   Write-Host "Version Info: $versioninfo"
+
+Compute hash in a script (Bash):
+
+.. code-block:: bash
+
+   versioninfo=$(cmfprocessor versioninfo)
+   echo "Version Info: $versioninfo"
+
