[PD-dev] Packaging question for Scheme for Pd

[Iain Duncan]

Thanks, IOhannes, that sounds sensible. So in order to make it as
homogenous as possible between people who build from source and those who
install the package (as ultimately I would like this to be extension
friendly at the C level), do you think it would be best to just have the
scm files live in the same directory as the C files in the source? Or is
there some suggested approach when using pd lib builder to make this
simple?

thanks
iain
