hm, looks like I have to intercept the inputs in order to turn the btex 
... into textexts (which happens with the main file)

what I actually need for this is a reader hook (just like we have a 
finder hook); I could use the finder hook to make a temporary file, but 
I wonder if that makes sense so let's first check if we can get a reader 
hook

(remind me in a few weeks anyway and use textext instead of btex/etex 
for the moment)
