+ "This package provides fundamental abstractions for doing asynchronous
+programming in R using promises. Asynchronous programming is useful for
+allowing a single R process to orchestrate multiple tasks in the background
+while also attending to something else. Semantics are similar to JavaScript
+promises, but with a syntax that is idiomatic R.")
