-# -------

-#  This variable controls whether we use zstream numbering or not for the

-#  build done for ystream for the Beta milestone, and increments a second
-#  number for each build. The third number is used for branched builds
-#  (eg.: for builds with security fixes or hot fixes done outside of the
-#  batch release process).
-#
-#  For example, with ZSTREAM unset or set to "no", all builds will contain
-#  a release with only the build number, eg.: kernel-<kernel version>-X.el*,
-#  where X is the build number. With ZSTREAM set to "yes", we will have
-#  builds with kernel-<kernel version>-X.Y.Z.el*, where X is the last
-#  RHEL_RELEASE number before ZSTREAM flag was set to yes, Y will now be the
-#  build number and Z will always be 1 except if you're doing a branched build
-#  (when you give RHDISTGIT_BRANCH on the command line, in which case the Z
-#  number will be incremented instead of the Y).
