    // We try to factorize the conditions in adjacent MSbuild items.
    // For this, we use several techniques that will:
    // * split elements into smaller elements, and conversely, merge elements with same conditions together
    // * move the conditions around
    // * find sets of identical elements (except for the condition) that can be expressed as a single element
    // In each step, extra care is taken to ensure that the meaning of the project stays the same.

    // However:
    // * Comments could move or become invalid
    // * Some element attributes containing line breaks will have them replaced with spaces.
    // * The absence of bugs is not guaranteed. Check the diff!
