+# == Class: elasticsearch::params
+#
+# This class exists to
+# 1. Declutter the default value assignment for class parameters.
+# 2. Manage internally used module variables in a central place.
+#
+# Therefore, many operating system dependent differences (names, paths, ...)
+# are addressed in here.
+#
+#
+# === Parameters
+#
+# This class does not provide any parameters.
+#
+#
+# === Examples
+#
+# This class is not intended to be used directly.
