CURL
A command line tool for getting or sending files using URL syntax.
Since cURL uses libcurl, it supports a range of common Internet protocols, currently including HTTP, HTTPS, FTP, FTPS, SCP, SFTP, TFTP, LDAP, LDAPS, DICT, TELNET, FILE, IMAP, POP3, SMTP and RTSP (the last four only in versions newer than 7.20.0 or 9 February 2010).
The name of the project is a play on 'Client for URLs', originally with URL spelled in uppercase to make it obvious that it deals with URLs. The fact that it can also be pronounced 'see URL' also helped; it works as an abbreviation for "Client URL Request Library" or the recursive version: "Curl URL Request Library".
Daniel Stenberg started writing cURL in 1997, as a way to transfer files via protocols such as HTTP, FTP, Gopher, and many more, via a command-line interface. Several other people made important and crucial contributions to the project. Distributed under the MIT License, cURL is free software.

Famous quotes containing the word curl:
“You will trail across the rocks
and wash them with your salt,
you will curl between sand-hills
you will thunder along the cliff
break retreat get fresh strength
gather and pour weight upon the beach.”
—Hilda Doolittle (1886–1961)
“An object among dreams, you sit here with your shoes off
And curl your legs up under you;”
