+#   Added a check to make sure user is in the staff group. This was a problem
+#   for me, and I think it was due to me migrating my account over several
+#   versions of OS X. I cannot verify that for sure, and it was tested on
+#   10.6.2 using the Directory Service command line utility and my laptop.
+#
+#   My assumptions are:
+#     - you are running OS X 10.6.x
+#     - your machine is not managed as part of a group using networked
+#       Directory Services
+#     - you have not recently killed any baby seals or kittens
