how do i make a document cap an objective?

like in Jagd, or in Carta2?

This is a tut map (This might be a bit old, I did this map a long time ago):

Here is a link to an old version (RMF) of dod_carta:

You will need the map (BSP) for the custom content; textures, models etc:

You could just use ripent to look at the entites and see how it's done.
