[Wylug-help] rpm question

[Emon]

Hi everybody

I am running openSUSE 10.3 with KDE desktop.

I installed the "pidgin" pkg with YaST which in turn installed a couple
of more pkgs to resolve dependencies.

My question is if I ever decide to uninstall "pidgin" how can I trace
those pkgs which were installed to resolve dependencies & uninstall
them?? either using YaST or from CLI.

My second question is about rpm & deb packages & thus might be very
contentions so a little bit of history first as I don't intend to start
a flame war here.......

this is how I started using linux & then moved on to different distros

RH-7.3 -> RH-8 -> Slackware-9.1 -> Slackware-10 -> Slackware-10.1 ->
Slackware-10.2 -> Slackware-11 -> NovelSuse-10.1 -> openSUSE-10.2 ->
openSUSE-10.3

as you have probably noticed I have no exposure to Debian or any of it's
derivative distros, but recently I have been listening to a lot of noise
regarding .deb pkgs from different people, so I even gave Ubuntu-7.04 a
shot when it was released... but I had other problems..

1)having shifted from M$-windows I have alway found KDE more appealing,
thus kind of dependent on it, so I didn't exactly try Ubuntu; rather
Kubuntu-7.04(DVD).

2) but I use applications which are sometimes very heavily dependent on
GNOME (pidgin, ekiga to name a few..). Sure many people suggested just
do "sudo apt-get foo" & everything will be fine, but I live in
Bangladesh & don't have broadband (internet is not a way of life here,
yet) and can't taken advantages of the facilities that modern package
managers offer may it be apt synaptic or YaST.

So by now you guys know why I had to ditch Kubuntu & stick to a distro
which by default had good support for both KDE & GNOME....

coming back to pkg management... I hear from a friend that when you
uninstall a .deb pkg in Debian (or any of it's derivative distros) the
pkg manager also uninstalls the pkgs those were installed to resolve
dependencies... sound pretty neat... is it true?? if so is it possible
to achieve this on rpm based distros??

Hope I did not offend/hurt any body's feelings
