Uninstalling packages

[monsee]

I would like uninstall (in my PC-BSD 9.0 x86_64 with installed desktops: XFCE and LXDE) some programs (that I have NOT installed: they comes "by own way", I think).
These programs are:
1) Brasero;
2) K3b;
3) Epiphany (the gnome browser)
... because I like Xfburn and I NOT-like at all Brasero (and I would non K3b, due the Xfburn presence). I don't like Ephipany, also, bat this is non so important...
It is possible, for me, uninstall these programs? (at lest, Brasero and K3b)
But there are not Brasero PBI or K3b PBI to uninstall... so, I think the right way can be to use the Terminal as root, but... wich command, exactly?
Thak you very much.

Let me guess - pkg_delete brasero\*

Thank you, friend! Thank you a lot! Your indication work very good.
Was needed to uninstall -before- four other gnome-packages, but -after this- your command work great.
Thank you!
