-# Builds VServer reference image. Requires the web and boot servers to
-# be up, which complicates bootstrap. Alternatively, we could require
-# the build server to host a local yum repository. Already, it is
-# required to run the same major version of yum as the nodes.
+# 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.
