The curl() function provides a drop-in replacement for base url()
with better performance and support for http 2.0, ssl (https://, ftps://),
gzip, deflate and other libcurl goodies. This interface is implemented
using the RConnection API in order to support incremental processing of
both binary and text streams. If you are looking for a more-user-friendly
http client, try the RCurl or httr packages instead.

The curl() and curl_download() functions provide highly configurable
drop-in replacements for base url() and download.file() with better performance,
support for HTTP 2.0, SSL (https://, ftps://), gzip, and other 'libcurl' goodies.
The core of the package implements a framework for performing fully customizable
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.
