+# == Class: puppet-haproxy
+#
+# A Puppet module, using storeconfigs, to model an haproxy configuration.
+# Currently VERY limited - assumes Redhat/CentOS setup. Pull requests accepted!
+#
+# === Requirement/Dependencies:
+#
+# Currently requires the ripienaar/concat module on the Puppet Forge and
+#  uses storeconfigs on the Puppet Master to export/collect resources
+#  from all balancer members.
+#
+# === Parameters
+#
+# [*enable*]
+#   Chooses whether haproxy should be installed or ensured absent.
+#   Currently ONLY accepts valid boolean true/false values.
+#
+# [*haproxy_global_options*]
+#   A hash of all the haproxy global options. If you want to specify more
+#    than one option (i.e. multiple timeout or stats options), pass those
+#    options as an array and you will get a line for each of them in the
+#    resultant haproxy.cfg file.
+#
+# [*haproxy_defaults_options*]
+#   A hash of all the haproxy defaults options. If you want to specify more
+#    than one option (i.e. multiple timeout or stats options), pass those
+#    options as an array and you will get a line for each of them in the
+#    resultant haproxy.cfg file.
+#
+#
+# === Examples
+#
+#  class { 'haproxy':
+#      enable                   => true,
+#      haproxy_global_options   => { 'log'     => "${::ipaddress} local0",
