-# Builds VServer reference image
+# Builds all reference image for slices.  To optimize for space it
+# will only build a complete base reference image and then
+# builds "stub" images that are just contain the additional files
+# and/or changes for a given reference image.  This is done to shrink
+# the RPM itself.  These will be pieced back together with the base
+# image by an init script that is installed on the node.
