How do you not include the trackback URL when using RSS/Maker?

I want to make feeds using RSS/Maker, but I don’t want the trackback to
madskills.com. I can’t figure out a parameter to turn it off.

Sample code:

require ‘rss/maker’
rss_content = RSS::Maker.make(“2.0”) do |m|
m.channel.link = “http://www.example.com
m.channel.title = “Test”
m.channel.description = “Test”
end
puts rss_content

Results in:

<?xml version="1.0" encoding="UTF-8"?>



Test
http://www.example.com
Test

I guess I could just remove it from rss_content before I write the file,
but
it seems silly that I’d have to do that. This is 1.8.6.

Thanks,

Patrick
