#!/usr/bin/env python2.6
"""
A quick script to install into your `Application Support/BBEdit/Scripts` folder.
This runs PyFlakes (requires PyFlakes to be installed at `/usr/local/bin` -
try ``/usr/bin/easy_install-2.6 pyflakes==0.4.0``) and reformats the results
so that they show up in BBEdit's search results / error / warnings window. Then
the errors can be stepped through one at a time.

I've bound this to control-shift-V. You must save your Python file first before
running the check.

Tuning a dataflow system is easy:

The First Rule of Dataflow Tuning:
* Ensure each stage is always ready to accept records, and
* Deliver each processed record promptly to its destination
