* major rewrite.
* fixed recursion ("attrib /s").
* started directory support ("attrib /s /d").
* updated help text.
*
* 14-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Unicode ready!
*
* 19-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
* Redirection ready!
*
* 21-Jan-1999 (Eric Kohl <ekohl@abo.rhein-zeitung.de>)
