   The maintainer would appreciate updates when new versions of
   <SPAN
CLASS="PRODUCTNAME"
>Red Hat Linux</SPAN

   would very much appreciate examples for <SPAN
CLASS="SYSTEMITEM"
>Linux</SPAN
> distributions that are dissimilar
   to <SPAN

>Red Hat Linux</SPAN
>; particularly
   <SPAN
CLASS="PRODUCTNAME"

   <SPAN
