//
// Resin file I/O roughly follows java.io with the exceptions:
// 1) All filenames are urls using \'/\' as the filename separator.
// 2) The myriad stream classes， readers， and writers are coalesced
// into a single stream object.
//
// This function recursively lists the directory contents.
//
// Example:
//
// top
// <ul>
// <li>sub1
// <li>sub2
// <ul>
// <li>subsub
// </ul>
// </ul>
//
function readdir(path)

for (file in path.list()) {
out.write("<li>");
readdir(path(file));
}
out.writeln("</ul>");
