There is a patch at SF that adresses this concept for spice.
It adds a spice-syntax attribut to the symbols and that attribut is 
interpreted by the netlister.

Me too, I'm currently playing with spice-models and template symbols. 
I'm just overwriting some attributes to match the current model/device.

Template attached.

All parameters are set by a script. The parameters are stored in an 
ini-style file that is easier to maintain:

[Q2PA1576Q,NXP00001]
symbol=pnp.sym
value=Q2PA1576Q
modelname=Q2PA1576Q
file=2PA1576Q.prm
refdes=Q?
pinseq_c=1
pinseq_b=2
pinseq_e=3
pinnr_c=C
pinnr_b=B
pinnr_e=E
footprint=none

I'll write more in a few weeks, I have to play a little bit more with 
it.

Regards
Werner
