 +====== Direct File Download ======
 +The goal is to provide users with a file download, directly in a php script rather than a hard link on a remote filesystem.  This allows us to implement user authentication prior to any files being available.
  
 +FIXME All of this will likely work, but so far is untested
 +
 +<code php>
 +<?
 +$dir="/path/to/file/";
 +if (isset($_REQUEST["file"])) {
 +    $file=$dir.$_REQUEST["file"];
 +    header("Content-type: application/force-download");
 +    header("Content-Transfer-Encoding: Binary");
 +    header("Content-length: ".filesize($file));
 +    header("Content-disposition: attachment; filename=\"".basename($file)."\"");
 +    readfile("$file");
 +} else {
 +    echo "No file selected";
