My confusion, I thought you meant command line not configuration file.

The boost program_options library handles configuration files as well as command lines.

The csound5/frontends/CsoundVST/CsoundFile.cpp file has examples of parsing CSD files, by reading a line at a time and looking for tags. It would be easy to adapt this to looking for equals signs.

Regards,
Mike

No worries, it was worth looking at anyway. ;)

I was thinking of doing much the same thing using the boost regex 
library, is that a bad idea? Is it overkill? It seems the natural way 
for me just because that's what I'm used to using with python, but 
perhaps it will be needlessly slow.

Thanks for the tip,
Iain
