 *
 * If you want content-types specified for each too, write them like:

 * 'name=@filename;type=image/gif,filename2,filename3'
 *
 * If you want custom headers added for a single part, write them in a separate
 * file and do like this:
 *
 * 'name=foo;headers=@headerfile' or why not
 * 'name=@filemame;headers=@headerfile'
 *
 * To upload a file, but to fake the file name that will be included in the
 * formpost, do like this:
 *
 * 'name=@filename;filename=/dev/null'
 *
 * This function uses curl_formadd to fulfill it's job. Is heavily based on
