build system

[Gor Gyolchanyan]

I had a few thoughts about integrating build awareness into DMD.
It would be really cool to add a flag to DMD to make it compile and
link in all import-referenced modules.
Also, it would be awesome to store basic build information in modules
themselves in the form of special comments (much like documentation
comments), where one could specify external build dependencies, output
type, etc.
There would be no need for makefiles and extra build systems. You'd
just feed an arbitrary module to the compiler and the compiler would
build the target, to which that module belongs (bu parsing build
comments and package hierarchies).
Wouldn't this be a good thing to have?
