This script will make a dump of the Django Book to your local filesystem so you can read it offline. Like say on a flight and you don’t want to pay 10 bucks for an hour of wifi. Even though you’re stoked you finally can, if you need/want to.

This script makes all the css links work so everything’s pretty. Also, Firefox by default won’t render index.html files as directory indexes when working in the ‘file://’ scheme, so this script rewrites internal links so that the index.html is explicit.

#!/bin/sh

# this script downloads a copy of the 2.0 django book, complete with css and
# sets it up so you can read it in-flight
