I've down loaded flirc.latest.x86_64.tar.gz and I've installed the needed Dependencies. The instructions say to cp the 99-flirc.rules rules to /etc/udev/rules.d/ , where are the 99-flirc.rules? Then is says to optionally copy flirc_util and flirc to /usr/local/bin/. Why is this an option? After this is done then what?
