haproxy stuff

##../modules/haproxy/init.pp
class haproxy {
  include
    '::haproxy::install',
    '::haproxy::config',
    '::haproxy::service'

    Class['::haproxy::install'] -> Class['::haproxy::config']
    Class['::haproxy::config'] ~> Class['::haproxy::service']
}

##../modules/haproxy/config.pp
class haproxy::config ( $haproxycfg ) {
  file { 'haproxy.cfg':
    ensure  => present,
    content => $haproxycfg,
    path    => '/etc/haproxy/haproxy.cfg',
    owner   => root,
  }
}

##now I wan't to declare or include ::haproxy somewhere, and set the $haproxycfg variable from haproxy::config
##Can I do this?


class {'haproxy':
  haproxycfg => 'template('cluster/haproxy.cfg.erb')',
}

The issue that I'm not clear on is that $haproxycfg is part of the haproxy::config class so I'm not sure how to set it when I declare ::haproxy as a resource somewhere.
