The deed is done. The trunk is identical to the commissioning branch as
I write this. Please do a fresh checkout of trunk/sim-recon to get
started on the new trunk. Updates of old check-outs of the trunk will be
problematic because of merge-markers that were present on the branch.
Let me know if you have problems.
