okular is not a 'stinking pdf reader'. Nice try. But just like konqueror
it is just a wrapper around kparts and is able to deal with a lot more
files than just pdf and postscript.

That is what 'modular' and 'code reuse' really means.

And the opposite to what gnome does. 'oh, there is an app. Hijack it and
gnomify it and make it dependent on 2 douzend gnome libs that all do the
same but nobody ever cleaned up'.

you know - useflags or tree would have been so much more meaningful...
