Ok, here's a dumb question from a Linux newbie:

I've downloaded kompozer-0.710-gcc4.0.3-1486.tar.gz.   Now, what do I do with it?  I can't find instructions anywhere on the forums to tell where to extract  the files  to or how to run  the install  once I have.  Does it need installing, or do I just extract  them and it'll work?

Also, is Kompozer still available via Synaptic Package Manager?  I  ran a  search and came up empty.

I'm running Ubunto Feisty Fawn.
