+# Copying Examples
+#
+# We used to use the copy module to transfer the openshift examples to
+# the remote. Then it started taking more than a minute to transfer
+# the files. As noted in the module:
+#
+#   "The 'copy' module recursively copy facility does not scale to
+#   lots (>hundreds) of files."
+#
+# The `synchronize` module is suggested as an alternative, we can't
+# use it either due to changes introduced in Ansible 2.x.
