HTTP HEAD request using curl??

Is it possible to do a http HEAD (instead of GET, POST or PUT) request using the php curl extension? I know that curl itself can do it, but I wasn't able to find the appropriate CURLOPT constant in the documentation for the php extension. I need to do a whole bunch of url calls but all I need is the headers, I don't have curl support compiled in and I probably won't bother compiling in if it can't do HEAD (I'll just use fopen). Has anybody been able to do this? Marc
