How do I know what a meta port installs?

[Per Berger]

Hi all!

I am running freebsd 5.3 RELEASE p5 and have installed several ports, so 
now I have X, gnome 2.10, firefox, openoffice and several other 
"goodies" installed. And most of it without a glitch! :-)

However, I have a question... (Of course, why else bother the list?? ;-) 
)

I have installed a couple of "meta" ports, for example gnome2. How can I 
see exactly which ports the meta port installs? I have tried to figure 
it out but failed...

I am right now installing "gnome2-power-tools" and can see that it 
installs apache (!) which causes some concern regarding configuration 
and security. So; what else did it install? How do I find out?
