I like your site -- succinct! We don't have a site yet -- coming soon, folks.
Using linux llr is simple. Just type in "./llr -m" and you are presented with a command-line menu that is equivalent to the menus seen in the windoze version. Once you have set up the input files etc., you can subsequntly run just "./llr" to bypass the menus. ( I use /etc/rc.local to start llr -- llr starts automatically if the box is rebooted.)
