+# == Define Resource Type: apache::balancer
+#
+# This type will create an apache balancer cluster file inside the conf.d
+# directory. Each balancer cluster needs one or more balancer members (that can
+# be declared with the apache::balancermember defined resource type). Using
+# storeconfigs, you can export the apache::balancermember resources on all
+# balancer members, and then collect them on a single apache load balancer
+# server.
+#
+# === Requirement/Dependencies:
+#
+# Currently requires the puppetlabs/concat module on the Puppet Forge and uses
+# storeconfigs on the Puppet Master to export/collect resources from all
+# balancer members.
+#
+# === Parameters
+#
+# [*name*]
+# The namevar of the defined resource type is the balancer clusters name.
+# This name is also used in the name of the conf.d file
+#
+# [*proxy_set*]
+# Hash, default empty. If given, each key-value pair will be used as a ProxySet
+# line in the configuration.
+#
+# [*collect_exported*]
+# Boolean, default 'true'. True means 'collect exported @@balancermember
+# resources' (for the case when every balancermember node exports itself),
+# false means 'rely on the existing declared balancermember resources' (for the
+# case when you know the full set of balancermembers in advance and use
+# apache::balancermember with array arguments, which allows you to deploy
+# everything in 1 run)
+#
+#
+# === Examples
+#
+# Exporting the resource for a balancer member:
+#
+# apache::balancer { 'puppet00': }
+#

+  $proxy_set = {},
+  $collect_exported = true,
