+GNU Emacs written in pure Emacs Lisp. It spawns an external producer process,
+such as @command{find} or @command{grep}, and filters the output asynchronously.
+The UI remains responsive, and results are shown via the Consult interface.
+Affe is experimental and best suited for small to medium projects.")
