# == 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.
