+turnaround projects like screen-scraping. It commonly saves
+programmers hours or days of work.
 
-1. Beautiful Soup won't choke if you give it bad markup. It yields a
-parse tree that makes approximately as much sense as your original
-document. This is usually good enough to collect the data you need
-and run away.
-
-2. Beautiful Soup provides a few simple methods and Pythonic idioms for
-navigating, searching, and modifying a parse tree: a toolkit for
-dissecting a document and extracting what you need. You don't have to
-create a custom parser for each application.
-
-3. Beautiful Soup automatically converts incoming documents to Unicode
-and outgoing documents to UTF-8. You don't have to think about
-encodings, unless the document doesn't specify an encoding and
-Beautiful Soup can't autodetect one. Then you just have to specify
-the original encoding.
-
-Beautiful Soup parses anything you give it, and does the tree traversal
-stuff for you. You can tell it "Find all the links", or "Find all the
-links of class externalLink", or "Find all the links whose urls match
-"foo.com", or "Find the table heading that's got bold text, then give
-me that text."
-
-Valuable data that was once locked up in poorly-designed websites is 
-now within your reach. Projects that would have taken hours take only 
-minutes with Beautiful Soup.
