/* Example application using the multi socket interface to download multiple

   multiple files at once, but instead of using curl_multi_perform and

   files in parallel, powered by libuv.

   curl_multi_wait, which uses select(), we use libuv.

   It supports epoll, kqueue, etc. on unixes and fast IO completion ports on

   Windows, which means, it should be very fast on all platforms..

   Written by Clemens Gruber, based on an outdated example from uvbook and

   some tests from libuv.

   Requires libuv and (of course) libcurl.
