>>> After the offline meeting today a few of us were discussing how to restore the sim-recon trunk (trunk/sim-recon) as the main line of development. Recall at the collaboration meeting there was consensus around copying the commission branch (branches/sim-recon-commissioning) onto the trunk at some point. Now that Justin has discovered the source of our previous problems with the branch (simulated data not reconstructing properly due to inappropriate calibration constants) it is beyond time that we do the copy, branch to trunk.
>>> 
>>> That having been said, one of us (David) pointed out rightly that some people probably have un-checked-in changes to their commissioning-branch code. As such the copy mentioned above, if done immediately, would leave their changes off the trunk. To avoid this we will delay the copy until 5:00 pm on Friday. In the meantime, please check-in any changes to the commissioning branch that represent real improvements. Those changes will then get swept to the trunk when we do the copy on Friday.
>>> 
>>> Note that if for some reason you are not able to make this deadline, your code changes are not lost forever. There are various ways to put them back on the trunk (description a bit too technical for this message). See me for assistance if needed.
>>> 
>>> After the copy is made, then the commissioning branch will be considered to be at end-of-life (apart from exceptions alluded to above, in reference to missing the deadline). All development after that should then begin with a fresh check-out of the trunk. We will make an announcement on this list when the copy is complete.
>>> 
>>> After we move off the branch, there will still be a need to analyze data from the Fall run obviously. To do that you need to build sim-recon against the commissioning branch of HDDS (i. e., you must still use the commissioning geometry). Alternately, you could continue to use the commissioning branch of sim-recon, just know that further improvements to that code base will not be coming in. For the upcoming run, since the trunk of HDDS (geometry) has the hydrogen target and the default beam line components, it should be used.

>>> Finally, if  you have objections to this plan, please let me know before Friday, 5 pm.
