+    """Provides a wrapper for the download.file function, making it possible to
+       download files over HTTPS on Windows, Mac OS X, and other Unix-like
+       platforms. The 'RCurl' package provides this functionality
+       (and much more) but can be difficult to install because it must be
+       compiled with external dependencies. This package has no external
+       dependencies, so it is much easier to install."""
