+     "This is an alternative mechanism for importing objects from packages.
+The syntax allows for importing multiple objects from a package with a single
+command in an expressive way.  The import package bridges some of the gap
+between using @code{library} (or @code{require}) and direct (single-object)
+imports.  Furthermore the imported objects are not placed in the current
+environment.  It is also possible to import objects from stand-alone @code{.R}
+files.")
