Title   : Rename weird directory/file names
Keywords: INVALID NAMES DIRECTORY FILE NETWARE 386 SUPERVISOR UTILITY

XREN allows to rename files and directories that cannot be renamed by
other DOS/NetWare tools.  XREN should not be used as a day-to-day tool,
but only as last rescue for visible, but inaccessible directories or
names.  It uses NetWares AFP APIs to allow greater flexibility in
directory and file names.  Public Domain by Wolfgang Schreiber
