First off, what a fantastic program.

I'm running version 4.3 under Kubuntu 14.04 (Linux). It is the version that is available in Muon Package Manager. I am having a problem installing version 4.6, as it is in '.tgz' format.

I have never figured how to manually install programs unless they are in '.deb. format - Which basically installs itself, all you do is open it and it self installs.

How do I install a '.tgz' file?
