# <rdar://problem/7226291> iPhoto - Missing Libraries after installing 10.6 - EyeFi has a bug that will put user data into /Volumes
# We need to examine /Volumes on the dead 'old' system that is been migrated from automatically during an upgrade install.
# If we find files or a non empty directoty, this could be eyeFi data, or other mispaced user files.

# This script will move such files to a top-level directory, passed as the second argument...
