P/S   For me, being able to edit the pcb as a text file, is one of its 
best features.

If there is something you can't do in the pcb editor,  just do it in a 
text editor.

I've also written a lot of python programs to create and manipulate 
boards, including routing.    In one project i wrote a script to do 
layouts and routing for minimum redundancy MIMO arrays.


But, of course, I cringed a little when I saw the note about a new PCB 
file format.
