Subject: Merging two Git-Repositories
Message-ID: <trinity-c6dbf360-5abe-43df-8428-85514195a7a6-1576574916643@3c-app-gmx-bs62>

Is it possible to merge one Git-Repository into another?  I have
developed two independent repositories A and B, and now I find that
B should be part of A in new sub-directory, e.g. A/B.  I want to
move B into A while keeping the whole development history of B.

How can I do that?
