You have came across a series of strange capital letters, with an unknown meaning. An excellent utility exists to solve that issue.
wtf is part of “bsd-games” package, that came to the Linux world from NetBSD project (thanks them!).
First, make sure that wtf is installed, by doing:
> rpm -q bsd-games bsd-games-2.13-386
If not, then install it first. Fortunately, the bsd-games package is included with openSUSE.
Start by typing:
> wtf AFAIK AFAIK: as far as I know
Discovering the rest will be left as an exercise to the suser. (SUSE user)
