a small ruby script to grab The Pragmatic Programmers Free Magazines (http://pragprog.com/magazines)

prag_mag_grabber.rb

#! /usr/bin/env ruby
require 'open-uri'
#wget could have been used but then it would
# 1) Make it dependent on an external program
# 2) Make it a one-liner ;)
#
#This script when executed will start downloading all the prag-mags
#in the current directory.
