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

[Mark M. Ito]

Folks,

I did not hear any objections to making the switch this afternoon at 5 
pm, so we are going to do the switch this afternoon (Tuesday) at 5 pm EDT.

N. B.: check in your changes to "src" before 5. "src" is getting deleted 
then and reconstituted in a new location. (See my previous message 
quoted below.)

Just to recap:

Instead of

svn checkouthttps://halldsvn.jlab.org/repos/trunk/src

making a directory "src" in the local directory, as we have done on the 
past, we will now do a

svn checkouthttps://halldsvn.jlab.org/repos/trunk/sim-recon

making a directory "sim-recon" that contains a "src" directory.

What about HALLD_HOME? Let's assume that the name of the local directory 
in the case above is /home/gluexuser/stuff. Then instead of

setenv HALLD_HOME /home/gluexuser/stuff

we will now say

setenv HALLD_HOME /home/gluexuser/stuff/sim-recon


In other words, it is still the case that "src" is in the directory 
pointed to by HALLD_HOME.

Let me know if any of this is not clear.
