	Sigh; true - it'll mostly speedup build time then; then again we could
filter them during / after generation I suppose.

	Right; that is done already as we merge to a library.

	Why do you think that Deps are 10% of the working directory ?

$ du -m workdir/unxlngi6.pro | tail -n 1
2906	unxlngi6.pro
$ du -m workdir/unxlngi6.pro/Dep | tail -n 1
1546	unxlngi6.pro/Dep

	For me that reads > 50% of the size.

	Is my workdir abnormally different to yours ? it's normal to have >
1.5Gb of 'stuff' in there I think - at least someone I sanity checked
with saw that too - IMHO it's too big.
