rake 系列命令
最熟悉的就是 rake db:create/migrate 對數據庫的操作，
也許這些也很少用的：
- rake -T 列出所有rake命令
- rake -T plugin 列出所有有關plugin的rake命令
- rake db:migrate version=0 清除數據庫數據和結構

$ rails new app_name
可選項:
- -d, database=xxx 指定安裝一個數據庫(mysql oracle postgresql sqlite2 sqlite3 ), 默認情況下是數據庫

- -f, freeze (凍結)freezes Rails在vendor/rails目錄
