/*
 * Pear File Uploader class. Easy and secure managment of files
 * submitted via HTML Forms.
 *
 * Leyend:
 * - you can add error msgs in your language in the HTTP_Upload_Error class
 *
 * TODO:
 * - try to think a way of having all the Error system in other
 *   file and only include it when an error ocurrs
 *
 * -- Notes for users HTTP_Upload >= 0.9.0 --
 *
 *  Error detection was enhanced, so you no longer need to
 *  check for PEAR::isError() in $upload->getFiles() or call
 *  $upload->isMissing(). Instead you'll
 *  get the error when do a check for $file->isError().
 *
 *  Example:
 *
 *  $upload = new HTTP_Upload('en');
 *  $file = $upload->getFiles('i_dont_exist_in_form_definition');
 *  if ($file->isError()) {
 *      die($file->getMessage());
 *  }
 *
