After a little bit of encouragement in the comments, Marc-André Cournoyer has come up with an excellent command-line generator for Monorail and ActiveRecord. I wanted to use the scaffolding generator to dump out editable templates for a quick administration system, but his initial release didn't support the .rails extension or Areas. Marc promptly wrote this in and he now delivers an excellent way of achieving what I wanted. Thank you Marc. Now make it do a UI for many-to-many relationships and I'll be a very happy man!
