+#
+#  This macro looks for a dist tag in the exact commit you
+#  checked out by cutting it into bits segmented by '.'
+#  and matching known values.
+#  If nothing is found it will fall back to a default
+#
+#
+
+# The actual work is done inside of this function
+#   set the "DEFAULT" and save it
+#   look through our known suffix lists
+#########
+# suffix list:
+#  ae   - Ansible Engine
+#  cf   - Cloud Forms
+#  dsrv - Directory Server
+#  ev   - Enterprise Virtulization
+#  op   - Open Shift
+#  ost  - Open Stack
+#  rhs  - Storage Server
+#  rt   - Real Time (MRG)
+#  sat  - Satellite Server
