I've been thinking about this as well - but I don't like this particular
implementation as it is too inflexible.

I want to decouple SIP and its build system (and possibly remove the latter
in SIP5). SIP should just provide metadata (file names, dependencies etc)
about the code it has generated. Different build systems can use the
metadata as they need to. The question is what format the metadata should
be in?

I'm inclined to stealing Mercurial's concept of templates - which is
effectively simple macro expansion - rather than imposing a fixed format
that a build system would then have to parse.

Suggestions welcome.
