I agree with you, but I would say in the current situation first things first.

Yes, in my thesis I made a fairly general stab at that kind of thing, 
including doing things like storing the proper feature extraction code in a 
database, if I recall right. However, I put the code to rest in non-showable 
state, as I made the mistake of using too many external libraries and too 
many plugins etc.  . Development became very painful and time-consuming for 
incertain benefits.

In the time I still believed in that above approach, I was against the simple 
one you are suggesting, now I am OK with it.

The greater number of greys is not a problem, as long as the greater number of 
greys etc. is added to your code in a way that the feature information file 
generated by the feature extractor is consistent with the features generated.

To come back to the discussion: I would say first things first. Let's get this 
code into the tree with minimal changes. Minimal in the sense that the 
already big installation hassle for people using the GIFT is not increased. 

Then I get a release out.

Then, if then there is time, we can look at neater things (IMHO).

Cheers,
Wolfgang
