Thanks for this App. I am trying to install this app on our Splunk which is running on a Linux machine. The README.txt file says "To install, extract the .spl file in $SPLUNK_HOME/etc/apps", but after downloading and extracting the SplunkforSnort.tar.gz compressed file, I do not see a .spl file in it. Is the instruction incorrect? Or is there another way to install SplunkforSnort ?
