Thanks for the code, but at the moment main target OS is Windows :(
 So I'd like to get somewhat closer to native support, using extra code
 like http://gnuwin32.sourceforge.net/packages/coreutils.htm isn't very
 good from maintenance point of view.
 So I'll try to get sl working. Did you found any difficulties using it?

 Best regards,
 Kirill
