Extensions tutorial > Rails error when generating controller

I have an idea for an extension to Radiant so I figured I would go
through the tutorial real quick to see how to start.

When I get to the part ‘Generating a Controller’, I type in the

script/generate extension_controller LinkRoll admin/links

and i get back:

The name ‘admin’ is reserved by Ruby on Rails.
Please choose an alternative and run this generator again.

hmmm. I know ‘Admin’ is in the list or reserved Rails keywords because
you can run ‘./script/runner ‘print Object.constants.sort.join(", ")’’
and see it listed. So how to get around this? The admin is part of
Radiant as well isn’t it?

Thanks for the help
