About map.inflected_resource

Hi,

In the routes.rb Typo file (readable at:
http://svn.typosphere.org/typo/branches/rails2/config/routes.rb) we can
see those line:

map.inflected_resource(:authors, :path_prefix => ‘/articles’)
map.inflected_resource(:categories, :path_prefix => ‘/articles’)
map.inflected_resource(:tags, :path_prefix => ‘/articles’)

Do you know the goal of them?

Thanks
