collectd_python_plugin turns option names into lowercase

Hi,
I'm trying to use the collectd_python_plugin to create a python.conf plugin file for collectd-carbon. If I use this code in a recipe:

collectd_python_plugin "carbon_writer" do
  options :LineReceiverHost=>"localhost", :LineReceiverPort=>2003, :DifferentiateCountersOverTime=>true, :LowercaseMetricNames=>true, :TypesDB=>"/usr/share/collectd/types.db", :HostPostfix=>"foo"
end

It creates the python.conf file where it should be, but the options become lower case:

# This file autogenerated by Chef
# Do not edit, changes will be overwritten
<LoadPlugin python>
  Globals true
</LoadPlugin>

<Plugin python>
  ModulePath "/usr/lib/collectd"
  Import "carbon_writer"

  <Module "carbon_writer">
    Linereceiverhost "localhost"
    Linereceiverport 2003
    Differentiatecountersovertime true
    Lowercasemetricnames true
    Typesdb "/usr/share/collectd/types.db"
    Hostpostfix "foo"
  </Module>
</Plugin>

The module options should be CamelCase and the plugin won't work unless this is so. It should look like:

        LineReceiverHost "myhost.mydomain"
        LineReceiverPort 2003
        DifferentiateCountersOverTime true
        LowercaseMetricNames true
        TypesDB "/usr/share/collectd/types.db"

Thanks,
Brian

Make that

collectd_python_plugin "carbon_writer" do
  options {
    :line_receiver_host=>"localhost", 
    :line_receiver_port=>2003,
    :differentiate_counters_over_time=>true,
    :lowercase_metric_names=>true,
    :types_db=>"/usr/share/collectd/types.db",
    :host_postfix=>"foo"}
end

The options writer automatically converts from the standard Ruby convention of lowercase-and-underscores to the collectd convention of initial caps.
