I feel the same way about libraries most of the time, but I think Bud 
and Rebuild are both sufficiently pervasive in the D community that it 
doesn't matter. For a new library I'm working on, I decided against 
Tango because it's not really an easy dependency to set up (i.e., not 
newbie-friendly). But I have no hesitation about requiring Bud to build 
it. I've long required Bud to build the Derelict libraries and that's 
worked just fine. In fact, I always recommend that users don't bother 
with the build script and just use Bud or Rebuild to compile Derelict 
packages with their apps.
