rails ruby script/rails で やる

railsの本(Head First)を買って勉強しているんだが、コマンドが変わったのか？
本のとおりにはできなかったので、その部分（といってもまださわりしかやってないのでそこの部分）をペースト。。。


andre@oem-desktop:~/railswork/tickets$ rails -v
Rails 3.0.3
andre@oem-desktop:~/railswork/tickets$ ruby script/rails -h
Usage: rails COMMAND [ARGS]

The most common rails commands are:
 generate    Generate new code (short-cut alias: "g")
 console     Start the Rails console (short-cut alias: "c")
 server      Start the Rails server (short-cut alias: "s")
 dbconsole   Start a console for the database specified in config/database.yml
             (short-cut alias: "db")
 new         Create a new Rails application. "rails new my_app" creates a
             new application called MyApp in "./my_app"

In addition to those, there are:
 application  Generate the Rails application code
 destroy      Undo code generated with "generate"
 benchmarker  See how fast a piece of code runs
 profiler     Get profile information from a piece of code
 plugin       Install a plugin
 runner       Run a piece of code in the application environment

All commands can be run with -h for more information.

[ruby script/server ...]や[ruby script/generate ...]ではなくなったよ。
