Well, that depends on what's in
the tarball, but the following should help you out a bit.
Open a terminal, go to the directory that contains your *.tar.gz file, and do the following;
tar -zxvf your_tarball.tar.gz
Once you get that done, go into the directory it creates and do an "ls -l
", you might see a file called "configure
If you see anything like "INSTALL
", or "doc
", get in there and start reading.
It'd help if you gave us the name or source URL where you obtained the tarball, too.
