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.

Tools to Transform 'cURL' Command-Line Calls to 'httr' Requests

Deciphering web/'REST' 'API' and 'XHR' calls can be tricky, which is one reason
why internet browsers provide "Copy as cURL" functionality within their "Developer Tools"
pane(s). These 'cURL' command-lines can be difficult to wrangle into an 'httr' 'GET' or
'POST' request, but you can now "straighten" these 'cURLs' either from data copied to the
system clipboard or by passing in a vector of 'cURL' command-lines and getting back a
list of parameter elements which can be used to form 'httr' requests. You can also make a
complete/working/callable 'httr::VERB' function right from the tools provided.

accessing the X11 clipboard
