    Note that alros.aseqcont.se() is deprecated, but alros.aseqcont.seSync() is not. (The callback parameter to alros.aseqcont.se() accepts parameters that are inconsistent with other alros.aseqcont.se callbacks. alros.aseqcont.seSync() does not use a callback.) So you can safely use alros.aseqcont.seSync() to synchronously check if a file exists.
