Hi folks,

I finally got around changing our build script to copy the calibrations 
files in our calibrations git repository into afs as part of the daily 
rebuild. Instead of having to read them from some hardcoded disk you can 
get to them under

$OFFLINE_MAIN/share/calibrations/<path in git>

e.g.
CrystalCalorimeter/mapping/crystals_v002.txt

in your code you can construct the filename and open it like:


#include <iostream>
#include <sstream>
#include <string>
#include <cstdlib>
#include <fstream>

using namespace std;

int main()
{
ostringstream filename;
filename << getenv("OFFLINE_MAIN") << 
"/share/calibrations/CrystalCalorimeter/mapping/crystals_v002.txt";
ifstream infile;
infile.open(filename.str().c_str(), ios_base::in);
 string str;
 while(getline(infile,str))
    {
     cout << str << endl;
    }
  infile.close();
}

Chris
