If D gets accepted for Google Summer of Code, I think this would be a
great idea for a project and I would be interested in implementing it as
a student. Although, it does seem overly ambitious so maybe only some of
this could be for the gsoc (and if I do this It'd be great to carry on

I've been thinking for quite some time to build a package management
system for D, lets call it dpac as an example. This is the ideas that I
have:

Basically copy how RubyGems works.
Use Ruby as a DSL for dpacsepc files which is used to create to create
the dpac file. This is an example for how a file used to build a package
could look like:

name "Foo Bar"
summary "This is the Foo Bar package"
version "1.0.0"
type :lib
author "Jacob Carlborg"
files ["lib.d"] # list of the files in the package
build :make # other options could be :dsss :cmake and so on
dversion 2 # D1 or D2

Build a dpac package out of the dpacspec file:

dpac foobar.dpacspec

Publish the package:

$ dpac publish foobar

Install the package:

$ dpac install foobar

A dpac package would just be a zip file (or some other type of archive)
containing all the necessary files to build the package and a file with
meta data.

All packages would be manged on a basic RESTful web server. Using GET to
download a package and POST to publish a package.

I'm working on a build system for D that I was thinking about to
integrate with the package management system. Then the build system
could track the files needed to build the package, making the "files"
attribute optional.

I also has a tool called DVM, https://bitbucket.org/doob/dvm , used for
installing and managing different versions of D compilers. I was
thinking about integrating DVM with the package management system to be
able to install different packages for different compilers.

I was thinking about something more similar to portage's ebuild system 
or arch's AUR. This would mean that the sources could be stored anywhere 
and just the info to build a package would be stored in a centralised 
location.


For publishing these build "scripts", again, AUR's system comes to mind, 
although perhaps something more controll(ed/able). Also, gentoo's 
sunrise overlay.


Of course, this comes with the downside of the user having to compile 
the packages on their end.
