flymake で間違っているところをハイライトし、エラーとかをミニバッファへ

とりあえず、 python とか難しいから、 flymake をフツーに入れてみる。

wget http://pypi.python.org/packages/source/p/pyflakes/pyflakes-0.4.0.tar.gz
tar xvzf pyflakes-0.4.0.tar.gz
cd pyflakes-0.4.0/
python setup.py install

で、 init.el は以下。よくわからないんだけど、 C とか Ruby とか一個一個書かなきゃ
いけないんだろうか。 javascript とかも難しそうだし・・・めんどくさい。
