Tremaで簡単なプログラムが実行できません。

質問

ホームにhello_world.rbを作りました。
class HelloController < Controller
def start
puts "Hello, World!"
end
end
と書きました。trema run hello_trema.rbとやると、大量のエラーがでました…
/var/lib/gems/2.2.0/gems/trema-0.8.4/lib/trema/command.rb:40:in `load': cannot load such file -- hello_trema.rb (LoadError)

from /usr/local/bin/trema:23:in `load'
from /usr/local/bin/trema:23:in `<main>'
ruby -vと打つとruby 2.2.3p173、trema -vと打つとVERSION 0.8.4と出てきます。どうすればよいでしょうか?よろしくお願いします。(Ubuntu14.04)

hello_world.rb と保存しているファイル名を hello_trema.rb へと変更して trema run hello_trema.rb と実行するか、
または、 hello_world.rb と保存しているファイル名をそのままにして trema run hello_world.rb と実行することで、表示されないでしょうか。

補足

trema run hello_world.rbと入力すると、
/home/vaio/hello_world.rb:1:in `<top (required)>': uninitialized constant Controller (NameError)

となります。
