def description # :nodoc:
    <<-EOF
The yank command removes a gem you pushed to a server from the server's
index.

Note that if you push a gem to rubygems.org the yank command does not
prevent other people from downloading the gem via the download link.

Once you have pushed a gem several downloads will happen automatically
via the webhooks.  If you accidentally pushed passwords or other sensitive
data you will need to change them immediately and yank your gem.

If you are yanking a gem due to intellectual property reasons contact
http://help.rubygems.org for permanent removal.  Be sure to mention this
as the reason for the removal request.
