Description:
Displays RSS, Atom, hAtom and OPML directly from originating website

by Benjamin C. Wiley Sittler, based on work by Johannes la Poutré and CommerceNet Consortium, LLC

RSS Panel X is a RSS/Atom/hAtom/OPML reader for Greasemonkey based on version 2.01 of Johannes la Poutré's excellent RSS Panel.

RSS Panel X has the following features:

* Displays feeds assocated with the webpage you're viewing. Supports several formats:
o hAtom 0.1 in HTML and XHTML,
o Atom 1.0 XML,
o RSS 0.9x, 1.0, and 2.0 XML, and
o OPML 1.0 XML.
* Works as a user script:
o Using Greasemonkey in Firefox and Flock,
o Using a modified Greasemonkey and xSidebar in SeaMonkey,
o Using Konqueror Userscript in Konqueror,
o As an Opera User JavaScript,
o Using Creammonkey in Safari, and
o Using Reify Turnabout Advanced or IE7Pro in Internet Explorer.
* Works as a bookmarklet in Firefox, Konqueror (as a Minitools bookmarklet), Shiira, K-Meleon (as a bookmarklet and as a same-layer hotlink), Safari, Opera, OmniWeb, and Internet Explorer (as a favelet.)
* Converts HTML and XHTML markup to plain text for readable display.
* Panel colors are selected based on page hostname.

  suggested by Mysteriously Nameless User ( http://userscripts.org/people/1976 )
  apparently similar to an unreleased version by Desert Fox ( http://userscripts.org/people/552 )
  - changed namespace again ( http://zoehep.xent.com/~bsittler/rsspanel.html )
  suggested by Mysteriously Nameless User ( http://userscripts.org/people/1976 )
  - new homepage ( http://zoehep.xent.com/~bsittler/rsspanel.html )
  - the bookmarklet now works as a Konqueror Minitool for RSS, Atom and hAtom feeds

  version 2.01-bsittler3 (experimental)
  - now works in Safari with Creammonkey 0.7 ( http://8-p.info/Creammonkey/ )
  - now listed on userscripts.org ( http://userscripts.org/scripts/show/6073 )

  version 2.01-bsittler2 (experimental)
  - now it's called "RSS Panel X" (i.e. "eXperimental" RSS Panel)
  - better overflow handling in Opera and MSIE
  - switched namespace to avoid collisions
  - repointed update URL to avoid spamming someone else w/my bugs
  - generated a new GUID for Greasemonkey Compiler
  http://www.letitblog.com/greasemonkey-compiler/

  - hAtom 0.1 support ( http://microformats.org/wiki/hatom )
  - Atom 1.0 support ( http://atomenabled.org/ )
  - multi-feed support
  - tested as GM, Opera and Turnabout user scripts, and as plain .js
  - new GM menu items for panel redisplay and feed reading
  - unofficial version by "Benjamin C. Wiley Sittler"

  version 2.01
  - minor tweak to fix compatibility with Safari 2.0.x and possible
  problems with other browsers as well.

  version 2.00
  - compatibility with Firefox 1.5 and GM 0.6.4 (release candidate)
  - enhanced security model: used XPCNativeWrapper to access
  native DOMParser object
  - added "check for updates" functionality; had to remove
  top level wrapper function to do this in a clean way.
  - Fix: apparently GM_XmlhttpRequest now needs fully qualified url.
  - reset margin on divs (some CSS sheets define a non zero value for
  every plain div, don's ask me why).
  - replace missing title and links with 'Untitled item #X" and
  #RSS_MISSING_LINK respectively.

  Version 1.18
  - fix for Firefox 1.5x; all events implemented in a W3C compliant way.
  Some code taken from "DOM-Drag" by Aaron Boodman, 2001
  http://www.youngpup.net/2001/domdrag
  Final version from Book Burro:
  http://www.lysator.liu.se/~jhs/userscript/bookburro/0.16.user.js

  Version 1.17
  - work around for Turnabout where GM_XmlhttpRequest returns
  resultXML as text string (= alias for resultText), Aaargh!
  - minor design tweaks for MSIE's CSS box model
  NOTE:
  - XMLHttpRequest is still very fragile under Turnabout ;-(

  Version 1.16
  - minor fixes to restore MSIE compatibility
  Welcome back, turnabout users!
  - fix with GM_log
  - call document as property of window (global) object
  (waiting for new GM version)

  Version 1.15
  - use GM_xmlhttpRequest() if available (GM 0.2.6+):
  loads any RSS feed, regardless of originating domain
  this means for instance that feedburner feeds are working.

  Version 1.14
  - logging through GM_Log if available (GM 0.3.3+)
  - namespace now points at the script's home page

  Version 1.13
  - fix for RSS feeds missing elements
  Thanks to Andy Dustman for hhis patch.

  Version 1.12
  - fix character encoding again (pure ASCII)

  Version 1.11
  - minior fix with character encoding (UTF-8)
  - generated GUID for Greasemonkey Compiler
  http://www.letitblog.com/greasemonkey-compiler/
  - GUID: {821ac008-72db-4ccd-94b9-722ccba5b28a}

  Version 1.10
  - Changed license to GPL
  Added by Brandan Lloyd:
  - Added title bar to make it draggable,
  - Allow the user to double-click to open and close so that
  clicking on a link doesn't toggle the view state,
  - Added a little icon for opening and with a single-click,
  - Added a scroll bar so that if the Reader is longer
  than the page the user can scroll.

  Version 1.03
  - Added a link to the discovered RSS feed (suggested by Nathan Howell)

  Version 1.02
  - Moved link to RSS home to mottom of list (suggested by Neil Kandalgaonkar)

  Version 1.01
  - Initial release
