 +As a test I installed ROOT via yum into the image. The first command here starts an interactive container.
 +
 +<code console>
 +-> docker run -i -t cern/slc6-base:6.5
 +[root@19035251353f /]# yum install root.x86_64

 +
 +Now I have my own SLC6.5 container with ROOT 5.34 installed.
 +
 +Next I played with trying to run a root script so I made one:
 +<code bash>
 +mkdir vlocal
 +vim vlocal/root_test.C
 +</code>
 +
 +<code c | root_test.C>
 +#include <string>
 +#include <iostream>
 +
 +int root_test(void){
 +   string test = "Hello World";
 +
 +   std::cout << test << "\n";
 +
 +   return 0;
 +}
 +</code>
 +
 +Then I wanted my container to mount my local directory and use this file:
 +
 +<code console>
 +-> docker run --volume=$PWD/vlocal:/vcont jtchilders/slc65:root534 root -b -q /vcont/root_test.C
