Very handy example.  Unfortunately it means that paths are 
embedded
in scripts, which is usually a bad idea.

I'm still looking for environment variables or config files that 
affect
dub's module include path.  Is there dub variable to give a 
general path
for all dependencies?  Since dub can read environment variables, 
this
may be a way to get a top-level module directory known to scripts 
without
hard coding paths.

Also, what do people do when generating .deb or .rpm packages for 
D
libraries?  They must reference some local library path in a 
general
fashion (I would think).

The only module paths I see referenced in:

   /etc/dmd.conf

are for phobos and the runtime import.  I guess I could just add 
another
one there.  Not sure if gdc also uses that file.
