          chmod [-i] mode filelist
               Set permissions of each of the files in the list
               filelist to mode, which is an absolute numeric mode or
               symbolic permissions as in the chmod(C) UNIX command.
               Normally absolute modes are assumed to be specified in
               octal.  However Tcl stores numbers internally as
               integers.  The -i option causes an absolute mode to be
               treated as a standard Tcl integer (decimal unless
               prefixed by "0" of "0x").
