[SOLVED] Dependencies: How can I know if a package is needed by other

Hi guys, how are you doing?

I'm fine, but I have a doubt that is killing me, it's the following:

I want to remove "fam" (because I added the word fam on the line "DAEMONS=(...)" on rc.conf because a X person posted it on an X blog, and now I think that person was wrong), but I don't know if there is any package that depends on fam.

So, I was wondering if there is any tool or script to know if X package is needed by Y, Z or more packages, I've seen that pacman has a lot of features, like seeking orphans, remove packages recursively, but I didn't found a feature to solve my problem. 
But maybe there is a script that performs a search in pacman's database on the field "dependencies" of all entries, and if there is any matches, the package would made appear in the output the results. Sadly, I can't program that script, because I know only a little bit of bash (I'm learning).

Sorry by my english mistakes, I hope you understood the message.

Cheers!

Simply try to remove it (-R switch), pacman will complain if anything depends on it, and will require confirmation anyway.

EDIT: I feel ashamed to post such a dirty solution. Actually, skunktrader is the winner.

pacman -Qi fam

Look for "Required By"

OMG!!!! I missed this field when I checked

 pacman -Qi <package> 

Thanks for your support, barto and skunktrader

Edit: I figured out: hal is required by samba... so I would not erase it.

Edit2: Mods, problem solved, it was much more simple than what i thought, feel free to close the topic
