Is there a definitive *nix command line tool for inspecting protocol buffers? : <p>I'm looking for a command-line utility that will, at a minimum, render binary protobuf data in human-readable form.  Filtering and selection options (along the lines of <code>cut</code> for text) would be nice, but the primary object is to make the data visible for debugging purposes.</p>

<p>If there is no definitive tool for the job, links to relevant packages are fine.</p>
