-# Builds VServer reference image
+# Builds all reference image for vservers. To optimize for space it
+# will only build a complete base vserver 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
+# vserver reference image by an init script that is installed on the
+# node.
