In the network graph hovering over charig/2-March commit I see a new
platform Nopsys added for SqueakNOS.

Thats cool !!!�� �� It'll be great to see this work with OpenSmalltalk.
However I notice its been added as a submodule.

Submodules bring additional complexity, so I thought there should be
some discussion on this topic.
Here are a couple of balanced introductions to submodules...

And a couple of cautions about using them...

Guido & Javier,
Have you used submodules successfully elsewhere?
Could you discuss your strategy using a submodule for the platform
code rather than adding directly into the opensmalltalk-vm repository?

I see your parent repository includes opensmalltalk-vm as a submodule
similar to how I *thought* Pharo was doing it, but wait on comment
from Esteban. .
�� [G] https://github.com/charig/Nopsys
�� [H] https://github.com/charig/Nopsys/blob/master/.gitmodules
So it seems�� ��platforms/Nopsys�� ��is a sub-sub-module.



Esteban,
I thought that you were using submodules to incorporate
opensmalltlak-vm into the pharo-vm,
but I can't see a .gitmodules file there.

So did you do it another way, or am I missing something?
Could you report your experience with adding opensmalltalk-vm into the
pharo-vm repository?
