    (description
     "entr is a zero-configuration tool with no external build or run-time
dependencies.  The interface to entr is not only minimal, it aims to be simple
enough to create a new category of ad hoc automation.  These micro-tests
reduce keystrokes, but more importantly they emphasize the utility of
automated checks.")
