Python static code analysis with pyflakes

Python tool pyflakes is focused on identifying common errors quickly without executing Python code. It can be installed with easy_install pyflakes. Since the tool doesn't import your code, you just specify a folder with source code:

user1@deby:~/devenv/trunk$ ../bin/pyflakes src/

Using pyflakes with IDE like PyDev make good sense since you see errors while you are typing.
