xorg , xfree86?

[ChadDavis]

Hey there.  What X system does my recent (installed yesterday ) debian etch system use? Isn't there adifference between xfree86 and xorg?  The docs I found on the debian site are for xfree86 but my system seems to have X11 / xorg stuff on it?  Sort me out if I'm clueless. 

Respect.
