Windows have NuGet for Visual Studio or console client.
It is difficult to create package for each OS. In this case we need a script that make a package for each OS or a one maintainer.
Or we need a one tool(script written in D) for the D (I mean D - the D Platform) and website with list of packages. Source code on bitbucket or github, full package available on repository for D Platform. Distribution via torrents or cdn.
I prefer second one.
