> The pcb file format is a little difficult to interpret and work with.

If you want to write to a pcb file it is straightforward, but parsing a 
random pcb/fp file can be a little problematic, I found some surprising
examples while scanning through [1] for pin data which i saved to [2].

Examples:
 Long lines:
Pin(0 0 70 36 "1" 257)Pin(0 100 70 36 "2" 1)Pin(0 200 70 36 "3" 1)Pin(0 300 70 36 "4" 1)Pin(0 400 70,,,

 Handling of ":
        Pin[15200 -15200 15000 2000 16200 7500 """10" 0x001]

 Numerical flags in [ ] notation
        Pin[0 20000 6000 2000 6600 3500 "" "1" 0x00004001]

and possible a few more.
A simple parser in perl for just "Pin" is in [3].
