/usr/share/doc/samba..xxx.xx.. (whatever)
There are lots of ways to look around on your hard drive. click on your home button and use konquerer, or nautilus, or open a shell and type cd /usr/share/sambaXXXX then 'ls' to list the contents of the folder. Don't be afraid to snoop around and 'look' on your hard drive, just read up before you start changing things
But that's a different post ;(
