What is Curl?

I use zen-cart, but it requires the hosting server installed Curl.
What is that for?

Curl is a command line tool to retrieve webpages. It is linux based although windows ports can be found. The best solution would be to ask your hosting provider to enable or install it. unless you have root access to the server in which case you should be able to find a tutorial on installing it via Google or the curl homepage: cURL and libcurl

Thanks very much.
