sPHENIX discussion of software

[John Haggerty <haggerty AT bnl.gov>]

Mike,

That seems to me to be a very good idea, to automate the construction of 
code that has to be duplicated all the time with minor differences.

I have recently become attached to MakeSelector in root, which allows 
you to construct an event loop on an arbitrary TTree *T by saying 
T->MakeSelector("mycode"), which then allows you to compile code with 
ACLiC and thus have an environment almost as convenient as T->Draw() in 
compiled code, which is the same idea of automated code generation.

I may not appreciate some of the nuances, but I think it would be nice 
to do something like this for sPHENIX as well, and I suspect it will 
engender a lively discussion on the sphenix list.  But it's the time of 
year when we look for fireworks;)
