Suppose you have a project with 2 subprojects that translate into products and you have them simply placed in 2 subfolders. Currently you need to write it like this:

import Qbs
Project
{
    DynamicLibrary
    {
        name: "Lib1"
        files: [ "lib1/*.cpp", "lib1/*.h"] 
    }
    DynamicLibrary
    {
        name: "Lib2"
        files: [ "lib1/*.cpp", "lib1/*.h"]
    }
}

Notice how the only difference betwen the two products is their name. Would not it be nice if one could do:

import qbs
import qbs.File

Project
{
    id: pro
    property stringList list:
    {
        var list = File.directoryEntries(qbs.sourceDirectory, File.Dirs | File.NoDotAndDotDot);
        var component = Qt.createComponent("Product.qml");
        for(var dir in list)
        {
            var product = component.createObject(pro);
            product.name: list[dir];
            product.files: [ list[dir] + "/*.cpp", list[dir] + "/*.h" ];
        }
{ 

Currently this will not work because this line:

var component = Qt.createComponent("Product.qml");

uses Qt.createComponent that is not available in Qbs and additionall "Product.qml" is likely not a regular QML component to be created like that. Another obstacle is probably component.createObject with parent being the id of Project but perhaps that would work as in QML.

I am not sure whether this is possible (with Qbs being dialect of QML) or if there is a better way to accomplish this (most likely). Interestingly this would be possible in qmake if qmake supported multiple projects per file but it would be possible for example to dynamically add subdirs in subdirs project.
