I think there are two levels to incremental compilation (IC).

1. File level IC. Meaning, if you have one file change, you only 
recompile
all files that depend on that directly or transitively. Finally, 
you relink.

2. Symbol level IC. Meaning, the compiler becomes a daemon, and 
you track
dependency on a symbol basis.

For 1. my goal with dud is to do that. My first target is to emit 
ninja files.
So IC is going to be the default, at least at first.

For 2. dud is build as a library first, meaning should the 
compiler
become a daemon at some point, libdud can be used to pull in 
packages from
code.dlang.org and resolve dub packages dependencies.
