-The curl() and curl_download() functions provide highly configurable
-drop-in replacements for base url() and download.file() with better
-performance, support for encryption (https, ftps), gzip compression,
-authentication, and other 'libcurl' goodies. The core of the package
-implements a framework for performing fully customized requests where
-data can be processed either in memory, on disk, or streaming via the
-callback or connection interfaces. Some knowledge of 'libcurl' is
-recommended; for a more-user-friendly web client see the 'httr' package
-which builds on this package with http specific tools and logic.
