Text for now.

I agree we need to address these in the future, and also binary 
distributions (e.g. .di files + .a/.lib files).

Consider a library "acme" consisting of three files: widgets.d, 
gadgets.d, fidgets.d in "http://acme.com/d/". It also depends on the 
external library monads on "http://nad.mo/d".

// User code:
pragma(lib, acme, "http://acme.com/d/");
import acme.widgets;
... use ...

// widgets.d
// Assume it depends on other stuff in the same lib
// and on monads.d
pragma(lib, monads, "http://nad.mo/d/");
import acme.gadgets, acme.fidgets, monads.io;

This is all that's needed for the compiler to download and compile 
everything needed.
