cURL - co s tím?

Zdravím, narazil jsem na modul podpory mod_rizvn_support kde mi tento modul oznamuje, že musím mít nainstalováno cURL. Vysvětlil by mi prosím někdo polopaticky o co se jedná? Děkuji

Tento popis z manuálu PHP vám nestačí?

PHP supports libcurl, a library created by Daniel Stenberg, that allows you to connect and communicate to many different types of servers with many different types of protocols. libcurl currently supports the http, https, ftp, gopher, telnet, dict, file, and ldap protocols. libcurl also supports HTTPS certificates, HTTP POST, HTTP PUT, FTP uploading (this can also be done with PHP's ftp extension), HTTP form based upload, proxies, cookies, and user+password authentication.

curl - zeptejte se na hostingu, pokud to sam nevite, zda tam curl mate
pokud ne, nechte si jej zapnout
pokud nevyhovii, musite jit jinam nebo se obejit
