[Halld-offline] switching from src to sim-recon

[Mark M. Ito]

Folks,

If you have been making changes to the code in the src directory lately, 
you are going to want to read this message carefully.

Software wise, I think I am ready to make the switch we discussed at the 
last Offline Meeting (see http://tinyurl.com/yhd8pmt). I have modified 
versions of the nightly build scripts prepared. There will be some 
clean-up to do after the transition occurs, but I don't think there will 
be major issues with the builds.

The cleanest way to make the change is to move the src directory to 
sim-recon/src in the Subversion repository. Not to belabour the point, 
but that means that the old src is deleted. This guarantees that no new 
code is checked into the old location, a good thing. This is not the 
only way to proceed, but is by far the easiest.

Whereas the transition is easy to make in the Subversion repository, it 
is not so trivial for versions of code checked out from the old tree and 
modified, especially if those modification are meant to be checked in 
someday. Their nominal home will have been deleted after the move.

To finesse this problem, I am proposing that we set a definite time to 
do the switch. Before that time, we are all responsible for checking in 
our own desired changes so that they all travel together to the new 
location. After that time, we all check out code from the new location 
and continue to work.

Let me propose that we do this Tuesday of next week, March 16, at 5 pm 
(for definiteness). That will make it a week since the meeting. If that 
is too soon, we could wait another week until the next Offline Meeting 
on March 23.

Let me know what you think.
