I found this interesting article (with a very unfriendly URL) that might be
useful to some curl users:

http://cedar.intel.com/cgi-bin/ids.dll/content/content.jsp?cntKey=Generic+Editorial%3a%3aws_scraping&cntType=IDS_EDITORIAL&path=1

(click on the printable version link to get all the pages visible at once)

It does include lots of kindly phrased references to curl...
