I am anxious to get to this demo, but can't seem to get started. I've managed to install Ruby 1.7.1 on my Mac OS X, as well as rails, and made sure there were no updates. But when I come to the command tp> rails demo I just get a message
Usage: rails new APP_PATH [options] with lots of text on how to create a new rails file. with no mention anywhere of a demo option.
I even tried rails new demo and then tried switching to the file that was created, but I still can't run the command ruby script/server - I just get a No such file or directory error.
