My lha2.12 has a -Or option that "skips datestamp check".   Does anyone know what that does?

I think that should be -Qr

       `-Qr' (add) Skip datestamp check  

          This option,  when  on, disables the datestamp comparison for
       the  update  (`u') and freshen (`f') commands, so that the files
       that  already  exist  in the archive will be replaced regardless
       of file modification dates.  

          This option is OFF by default for all commands but `r'.
