+# ############################################################################
+# Helper functions for building packages from the trunk or branches. To use
+# this .bbclass simply inherit from it in your conf/local.conf.
+#
+# - get_branch() helps to construct the package name when fetching by 
+#   extracting the directory name above the "build" directory containing the
+#   oe environment and bitbake. That directory name is usually the branch in
+#   which the package is located in the svn with one exception: "unstable"
+#   is synonymous for "trunk". In the package you can then use the ${BRANCH}
+#   variable within the svn (or cvs) url for the package.
+#
+# - get_tomorrow() makes sure the latest version of a package is fetched. To
+#   use it, set the SRCDATE to ${TOMORROW}.
