Hi Matthew,

I will try to find time this month to look into your stuff.

The pictures on the web page are promising.

In the mean time I will start a bug report on launchpad and upload the 
files.

I will also add a development branch in my local Github repository 
(https://github.com/bert/pcb/branches) for test driving and adding 
improvements if/where needed.

Thanks and kind regards,

Bert Timmerman.
