Build tools.

[David Brown]

Just curious what people are using to build programs in D.  There is
<http://www.dsource.org/projects/build>, but it doesn't even compiler with
gdc-0.24, hitting 'macro' as a keyword.

I've managed to construct some python code that runs gdc verbosely, and
parses the output in order to generate dependency information, but it seems
kind of silly to write this when it looks like other tools do the job.

Thanks,
