DIP11: Automatic downloading of libraries

[Mike Wey]

First i didn't read all of the posts in this thread, so some of these 
might already be answered.

In the first paragraph the DIP talks about Automatic downloading of 
*libraries* while all the posts here talk about downloading files.
This is also reflected in the "Package case" paragraph since the 
compiler / separate tool will first try to download a .di file.
Which generally is a d import or header file, which doesn't need to 
include the implementation, so the compiled library should also be 
downloaded or linking would fail, right?

Also the proposal doesn't do anything with versioning, while larger 
updates will probably get a different url, bug fixes might still 
introduce regressions that silently break an application that uses the 
library. And now you'll have to track down witch library introduced the 
bug, and more importantly your app broke overnight and while you didn't 
change anything. (other that recompiling)

To find out how downloading the files would work i did some tests with GtkD.

Building GtkD itself takes 1m56.
Building an Helloworld app that uses the prebuild library takes 0m01.

The Helloworld app need 133 files from GtkD.
Building the app and the files it needs takes 0m24.

The source of the HelloWord application can be found here:
