If I'm installing from source, do I need to keep the extracted tarball directory? So if I download the git tarball. I then do:

```
tar -xvzf git.tar.gz

```

This will create a `git.x.x`. directory, into which I `cd`, then run `./configure` etc. Once I'm done with this process, and `git`, or whatever is installed, do I need to keep the original `git.x.x` extracted directory, or is that just used for compiling the program?

I'm somewhat confused by all the directories, and folders used for programs.
