In D a file with the extension *.json is used to describe packets 
that are included in your project, the dependency manager DUB.

For example, you can install Eclipse with DDT and create a 
project with DUB. The file dub.json write the following:
-----
{
     "name" : "myDupApp",
     "description" : "Carbon - Test.",
     "dependencies" : {
         "carbon": "~>1.4.1"
     }
}
-----

Save the file (Ctrl + S). Then in your project with DUB 
downloaded package `carbon`:
http://code.dlang.org/packages/carbon

After that you can safely use the package `carbon`:
-----
import std.stdio, carbon.linear;;

void main() {
     auto m = matrix!(2, 3, (i, j) => i * 3 + j);
     writeln(m); // [[0, 1, 2], [3, 4, 5]]
}
