    (description
     "@acronym{entr, event notify test runner} reads a list of file names from
standard input and executes a given command (including arguments) whenever any
of them change.  It aims to facilitate rapid feedback and automated testing.

For example, you can use @command{entr} to automatically invoke @command{make}
each time you modify a source code file.  It supports interactive utilities and
doesn't waste resources by polling for changes.")
