+# == Define Resource Type: haproxy::balancermember
+#
+# This type will setup a balancer member inside a listening service
+#  configuration block in /etc/haproxy/haproxy.cfg on the load balancer.
+#  currently it only has the ability to specify the instance name,
+#  ip address, port, and whether or not it is a backup. More features
+#  can be added as needed. The best way to implement this is to export
+#  this resource for all haproxy balancer member servers, and then collect
+#  them on the main haproxy load balancer.
+#
+# === 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
+#
+# [*name*]
+#   The title of the resource is arbitrary and only utilized in the concat
+#    fragment name.
+#
+# [*listening_service*]
+#    The haproxy service's instance name (or, the title of the
+#     haproxy::listen resource). This must match up with a declared
+#     haproxy::listen resource.
+#
+# [*ports*]
+#     An array or commas-separated list of ports for which the balancer member
+#     will accept connections from the load balancer. Note that cookie values
+#     aren't yet supported, but shouldn't be difficult to add to the
+#     configuration. If you use an array in server_names and ipaddresses, the
+#     same port is used for all balancermembers.
+#
+# [*server_names*]
+#     The name of the balancer member server as known to haproxy in the
+#      listening service's configuration block. This defaults to the
+#      hostname. Can be an array of the same length as ipaddresses,
+#      in which case a balancermember is created for each pair of
+#      server_names and ipaddresses (in lockstep).
+#
+# [*ipaddresses*]
+#      The ip address used to contact the balancer member server.
+#      Can be an array, see documentation to server_names.
+#
+# [*options*]
+#      An array of options to be specified after the server declaration
+#       in the listening service's configuration block.
+#
+#
+# === Examples
+#
+#  Exporting the resource for a balancer member:
+#
+#  @@haproxy::balancermember { 'haproxy':
+#    listening_service => 'puppet00',
+#    ports             => '8140',
+#    server_names      => $::hostname,
+#    ipaddresses       => $::ipaddress,
+#    options           => 'check',
+#  }
+#
+#
+#  Collecting the resource on a load balancer
+#
+#  Haproxy::Balancermember <<| listening_service == 'puppet00' |>>
+#
+#  Creating the resource for multiple balancer members at once
+#  (for single-pass installation of haproxy without requiring a first
+#  pass to export the resources if you know the members in advance):
+# 
+#  haproxy::balancermember { 'haproxy':
+#    listening_service => 'puppet00',
+#    ports             => '8140',
+#    server_names      => ['server01', 'server02'],
+#    ipaddresses       => ['192.168.56.200', '192.168.56.201'],
+#    options           => 'check',
+#  }
+#  
+#  (this resource can be declared anywhere)
+#
+define haproxy::balancermember (
+  $listening_service,
+  $ports,
+  $server_names = $::hostname,
+  $ipaddresses  = $::ipaddress,
+  $options      = ''

+# == Define Resource Type: haproxy::listen
+#
+# This type will setup a listening service configuration block inside
+#  the haproxy.cfg file on an haproxy load balancer. Each listening service
+#  configuration needs one or more load balancer member server (that can be
+#  declared with the haproxy::balancermember defined resource type). Using
+#  storeconfigs, you can export the haproxy::balancermember resources on all
+#  load balancer member servers, and then collect them on a single haproxy
+#  load balancer server.
+#
+# === 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
+#
+# [*name*]
+#    The namevar of the defined resource type is the listening service's name.
+#     This name goes right after the 'listen' statement in haproxy.cfg
+#
+# [*ports*]
+#    Ports on which the proxy will listen for connections on the ip address
+#    specified in the virtual_ip parameter. Accepts either a single
+#    comma-separated string or an array of strings which may be ports or
+#    hyphenated port ranges.
+#
+# [*ipaddress*]
+#    The ip address the proxy binds to. Empty addresses, '*', and '0.0.0.0'
+#     mean that the proxy listens to all valid addresses on the system.
+#
+# [*mode*]
+#    The mode of operation for the listening service. Valid values are 'tcp',
+#     HTTP', and 'health'.
+#
+# [*options*]
+#    A hash of options that are inserted into the listening service
+#     configuration block.
+#
+# [*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 haproxy::balancermember 
+#    with array arguments, which allows you to deploy everything in 1 run)
+#
+#
+# === Examples
+#
+#  Exporting the resource for a balancer member:
+#
+#  haproxy::listen { 'puppet00':
+#    ipaddress => $::ipaddress,
+#    ports     => '18140',
+#    mode      => 'tcp',
+#    options   => {
+#      'option'  => [
+#        'tcplog',
+#        'ssl-hello-chk'
+#      ],
+#      'balance' => 'roundrobin'
+#    },
+#  }
+#
+# === Authors
+#
+# Gary Larizza <gary@puppetlabs.com>
+#
+define haproxy::listen (
+  $ports,
+  $ipaddress        = [$::ipaddress],
