Well, the "give me all source on the command line" thing is a C legacy 
where compiler simply couldn't deduce the files required to build the 
project.  In D it's possible and there probably should be an -auto 
option in DMD.  Maybe -version=auto could be defined for the first 
module then.  I'm not sure.

Bud supports D2.  This means it's being maintained.

Please read again:

It's completely up to the build system which way to go, it has all the 
flexibility.
