That is very doable, but if you have a PCB-preprocessor, pcb's error 
messages don't any longer relate to your input file, it relates to the 
in-between-file, and then you must know both the input file format, 
pcb's file format and how the preprocessor operates.

Soo, when it works, great!
When it fails, double pain.
