Comment 9 for bug 1744832

Dr. Mitch-

It's perfectly possible to run pcb out of the source tree. So, you can build it and test it without installing it (don't do the "make install" step. Thus, it remains entirely parallel to your existing system, and shouldn't disrupt anything.

The way I've implemented it, when a file is saved, if the all the via mask values in the styles are set to zero, then it will save in the older format. The via mask is saved as the last parameter in the styles definition, so, if your parser can handle an additional field in the line, there should be no problem. If you're using str.split(" ") to break the parameters, then your output list will just be one element longer. The order of the parameters hasn't changed, so, no existing code should break.

Thanks,
