The --libcurl option is one way to find out.

From the manual for CURLOPT_POSTFIELDS: This POST is a normal
application/x-www-form-urlencoded kind...To make multipart/formdata
posts check out the CURLOPT_HTTPPOST option.

From the manual for CURLOPT_UPLOAD: "If the protocol is HTTP, uploading
means using the PUT request." Don't use this if you want a POST.

Use curl_formadd to create the right post data and CURLOPT_HTTPPOST to
specify it. Take a look at the postit2.c example program to start.
