-Handles RSS 0.9x, RSS 1.0, RSS 2.0, Atom feeds
-
-Things it handles that choke other parsers:
-- bastard combinations of RSS 0.9x and RSS 1.0
-- illegal 8-bit XML characters
-- naked and/or invalid HTML in description
-- content:encoded, xhtml:body, fullitem
-- guid
-- elements in non-standard namespaces or non-default namespaces
-- multiple content items per entry (Atom)
-- multiple links per entry (Atom)
-
-Other features:
-- resolves relative URIs in some elements
- - uses xml:base to define base URI
- - uses URI of feed if no xml:base is given
- - to control which elements are resolved, set _FeedParserMixin.can_be_relative_uri
-- resolves relative URIs within embedded markup
- - to control which elements are resolved, set _FeedParserMixin.can_contain_relative_uris
-- sanitizes embedded markup in some elements
- - to allow/disallow HTML elements, set _HTMLSanitizer.acceptable_elements
- - to allow/disallow HTML attributes, set _HTMLSanitizer.acceptable_attributes
- - to control which feed elements are sanitized, set _FeedParserMixin.can_contain_dangerous_markup
- - to disable entirely (NOT RECOMMENDED), set _FeedParserMixin.can_contain_dangerous_markup = []
-- optionally tidies embedded markup
- - fixes malformed HTML
- - converts to XHTML
- - converts character entities to numeric entities
- - requires mxTidy <http://www.lemburg.com/files/python/mxTidy.html>
+Handles RSS 0.9x, RSS 1.0, RSS 2.0, CDF, Atom feeds

#REVISION HISTORY
#1.0 - 9/27/2002 - MAP - fixed namespace processing on prefixed RSS 2.0 elements,
#2.7.5 - 1/15/2004 - MAP - added workaround for malformed DOCTYPE (seen on many
# blogspot.com sites); added _debug variable
#2.7.6 - 1/16/2004 - MAP - fixed bug with StringIO importing
-#3.0 - MAP - parse entire feed with real XML parser (if available); added several
-# new supported namespaces; fixed bug tracking naked markup in description;
-# added support for enclosure; added support for source; re-added support for
-# cloud which got dropped somehow; added support for expirationDate; fixed
-# xml:lang inheritance; fixed multiple bugs tracking xml:base URI, one for
-# documents that don't define one explicitly and one for documents that define
-# an outer and an inner xml:base that goes out of scope before the end of the
-# document; fixed bug parsing multiple links at feed level; added feed type and
-# version detection, results["version"] will be one of SUPPORTED_VERSIONS.keys()
-# or empty string if unrecognized; added support for creativeCommons:license and
-# cc:license; added support for full Atom content model in title, tagline, info,
-# copyright, summary; fixed bug with gzip encoding (not always telling server
-# we support it when we do); support Atom-style author element in author_detail

+#3.0b7 - 1/28/2004 - MAP - support Atom-style author element in author_detail
# (dictionary of "name", "url", "email"); map author to author_detail if author
-# contains name + email address; better handling of empty HTML tags (br, hr, img,
-# etc.) in embedded markup, in either HTML or XHTML form (<br>, <br/>, <br />);
-# fixed CDATA handling in non-wellformed feeds under Python 2.1
+# contains name + email address
+#3.0b8 - 1/28/2004 - MAP - added support for contributor

+# xml.util.iso8601
+#3.0b11 - 2/2/2004 - MAP - added 'rights' to list of elements that can contain
+# dangerous markup; fiddled with decodeEntities (not right); liberalized
+# date parsing even further
+#3.0b12 - 2/6/2004 - MAP - fiddled with decodeEntities (still not right);
+# added support to Atom 0.2 subtitle; added support for Atom content model
+# in copyright; better sanitizing of dangerous HTML elements with end tags
+# (script, frameset)
+#3.0b13 - 2/8/2004 - MAP - better handling of empty HTML tags (br, hr, img,
+# etc.) in embedded markup, in either HTML or XHTML form (<br>, <br/>, <br />)
+#3.0b14 - 2/8/2004 - MAP - fixed CDATA handling in non-wellformed feeds under
+# Python 2.1
+#3.0b15 - 2/11/2004 - MAP - fixed bug resolving relative links in wfw:commentRSS;
+# fixed bug capturing author and contributor URL; fixed bug resolving relative
+# links in author and contributor URL; fixed bug resolvin relative links in
+# generator URL; added support for recognizing RSS 1.0; passed Simon Fell's
+# namespace tests, and included them permanently in the test suite with his
+# permission; fixed namespace handling under Python 2.1
+#3.0b16 - 2/12/2004 - MAP - fixed support for RSS 0.90 (broken in b15)
+#3.0b17 - 2/13/2004 - MAP - determine character encoding as per RFC 3023
+#3.0b18 - 2/17/2004 - MAP - always map description to summary_detail (Andrei);
+# use libxml2 (if available)
+#3.0b19 - 3/15/2004 - MAP - fixed bug exploding author information when author
+# name was in parentheses; removed ultra-problematic mxTidy support; patch to
+# workaround crash in PyXML/expat when encountering invalid entities

+#3.0b22 - 4/19/2004 - MAP - changed 'channel' to 'feed', 'item' to 'entries' in
+# results dict; changed results dict to allow getting values with results.key
+# as well as results[key]; work around embedded illformed HTML with half
+# a DOCTYPE; work around malformed Content-Type header; if character encoding
+# is wrong, try several common ones before falling back to regexes (if this
+# works, bozo_exception is set to CharacterEncodingOverride); fixed character
+# encoding issues in BaseHTMLProcessor by tracking encoding and converting
+# from Unicode to raw strings before feeding data to sgmllib.SGMLParser;
+# convert each value in results to Unicode (if possible), even if using
+# regex-based parsing
