+     "This package provides an IO library for testing interactive command line
+programs.  Proctest aims to simplify interacting with and testing terminal
+programs, providing convenience functions for starting programs and reading
+their output.  All blocking operations support timeouts so that misbehaving
+programs cannot block your test pipeline.  Find more examples and contribute
+at @url{https://github.com/nh2/proctest}.")
