+====== Using Singularity for cvmfsexec ======
+One can also setup cvmf on any LCRC nodes as this:
+<code>
+source /soft/hep/CVMFSexec/setup.sh
+</code>
+Then check:
+<code>
+ls /cvmfs/
+</code>
+You will see the mounted directory (SL7):
+<code>
+atlas-condb.cern.ch/      atlas.cern.ch/  cvmfs-config.cern.ch/  sft-nightlies.cern.ch/  sw.hsf.org/
