When running rdoc the folders 'images' and 'js' are not copied to the doc dir

I am running rdoc 2.5.9 and when I generate rdoc with the default 'Darkfish' template just by running:

rdoc app README

in my rails root folder. All the files are generated but th开发者_运维问答e 'images' and 'js' folder is missing in the doc directory. So I need to copy them manualy.

I have the following versions:

gem 1.3.7
ruby 1.8.7
Rails 2.3.8
rvm 0.1.41

Do I need to specify more command-line arguments to get those folders copied?

This is a known bug. More information about it here.
