craigwatch / libcraigscrape
An easy library to do the heavy lifting between you and Craigslist's posting database. Given a URL, libcraigscrape will follow links, scrape fields, and make ruby-sense out of the raw html from craigslist's servers. libcraigscrape was primarily developed to support the included craigwatch script. See the included craigwatch script for examples of libcraigscape in action, and (hopefully) to serve an immediate craigscraping need.
