/**
 * <p>High level API for processing file uploads.</p>

 * <a href="http://www.ietf.org/rfc/rfc1867.txt">RFC 1867</a>.  Use {@link

 * of {@link org.apache.commons.fileupload.FileItem FileItems} associated
 * with a given HTML widget.</p>
 *
 * <p>How the data for individual parts is stored is determined by the factory
 * used to create them; a given part may be in memory, on disk, or somewhere
 * else.</p>
