+# This script is meant to be run from Jenkins to make an initial clone of the
+# CI repository.
+#
+#  - If CI_ROOT is set, we assume that a parent job has already cloned required
+#    repositories; so we skip further cloning. However, in order to prevent this
+#    job from potentially cleaning up the filer workspace (which is the
+#    responsibility of the parent job which did the original clone), we unset
+#    the FILER_WS variable in the env file.
+#
+#  - Otherwise, we call clone_repos.sh to have all required repositories to be
+#    cloned.
+#
+# Note that, since this file resides in the repository itself, a copy of this
+# file must be 'wget'. I.e., any changes to to this file must be committed first
+# to the CI repository master for it to take effect!
