+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

+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
