TYPO3 Core

I've got an question about installing Typo3 in the root.
Because normally you have 2 maps:
1. The source of typo3
and
2. The Dummy map.

But i want to have everything in my root, because all visitors will see mysite.com/site
And i want the normale URL without /site.

I heard somebody saying that you can do in with creating new symlinks.
But i never worked with symlinks. So i don't know where to start and GOOGLE is not helping me either..

Is there an installion package where with is standard?
I saw at the packages by Typo3 that there is an .zip named: Source + Dummy. Is that the one? If that is, i've another problem.

I can't login width SSH, and wiith ftp it is not alowed to unzip things.
And my filemanager ( with DirectAdmin panel ) i only can UnTarGz.

I can't believe this isn't possible in Typo3 wihout changing symlinks...

Gr,

Justin
