802The benefit of using subtree merge is that it requires less
803 administrative burden from the users of your repository. It works with
804 older (before Git v1.5.2) clients and you have the code right after
805 clone.

810However if you use submodules then you can choose not to transfer the
811 submodule objects. This may be a problem with the subtree merge.

816Also, in case you make changes to the other project, it is easier to
817 submit changes if you just use submodules.
