Deactivating a port

[John Ridgway]

Friends -
I'm creating some new ports -- stuff from CTAN for TeX, and I am  
discovering a real need for a pre- or post- deactivate hook  
(preferably both, but I could live with only post-).  What are the  
chances that this functionality could get in to the base?  The reason  
is that when adding fonts to a TeX tree one needs to run updmap-sys  
to make the fonts available, but when they go away again we need to  
run updmap-sys again...

I just like to clean up after myself. :-)

Peace
- John
