    This script enables you to create interaction between PmWiki and delicious.com. 

    To use this script, copy it into the cookbook/ directory
    and add the following line to config.php (or a per-page/per-group
    customization file). 
    include_once("$FarmD/cookbook/delicious.php");

    The script will generate a linkroll or tagroll.
    The simplest linkroll can be created by using the markup (:linkroll user=foo:)
    where foo is the desired delicious username, creating a roll of 10 recent links.
    Similarly (:tagroll user=foo:) creates a complete tag cloud of user foo.

    The script can also add a delicious.com tagometer, by using the markup (:deliciousbadge:).

    The recipe is derived from the delicious.com help pages, specifically:
    http://delicious.com/help/tagrolls
    http://delicious.com/help/linkrolls
    http://delicious.com/help/tagometer

    The following is a list of arguments for tagrolls and linkrolls:

    For (:linkroll:)
	* user: delicious.com username (required)
	* number: the number of links you want to display (default: 10)
	* sort: recent or alpha (default: recent)
	* tags: Limit the linkroll by tag(s). Multiple tags use the syntax 'tag+tag'
	* icon: large, small, rss, or none (default: large)
	* title: text to display as a header (default: My Delicious Bookmarks) - due to a bug, please use title='my title' rather than title="my title"
	* showtags: true or false (default: false) - include the tags associated with each link
	* shownotes: true or false (default: false) - include the notes associated with each link 
	* showname: true or false (default: false) - displays username at the bottom, with a link to user's delicious page
	* showadd: true or false (default: false) - displays link to add user to your delicious network 

    For (:tagroll:)
	* user: delicious.com username (required)
	* number: number of tags to display (default: empty / '')
	* sizerange: in the syntax '8-25', the lowest and highest text size used for display (default: 12-35)
	* title: text to display as a header (default: 'My Delicious Bookmarks')
	* sort: options are freq (frequency) or alpha (default: alpha)
	* flow: cloud or list (default: cloud)
	* color1/color2: color1 is the least frequent tag, color2 is the most frequent (colors 
      are used on a gradient between color1 and color2).  must use html colors, 
      no # (aka like this: '000099')
	* counts: true or false (defaut: false) - include the frequency of each tag
	* showicon: true or false (default: false)
	* showname: true or false (default: false) - displays username at the bottom, with a link to user's delicious page
	* showadd: true or false (default: false) - displays link to add user to your delicious network 


	For (:tagometer:)
	Users can declare their own tagometer badge using the copy&paste method from http://delicious.com/help/tagometer via $DeliciousTagometerFmt = 'yourjavascript';
	* size: wide or tall (default: wide)
	* icon: true or false (default: true) - shows or hides delicious icon
	* timesSaved: true or false (default: true) - shows or hides # of times saved
	* graph: true or false (default: true) - shows or hides graph
	* tags: true or false (default: true) - shows or hides tag

	Declare your own set of default values via $DeliciousTagometerDefaults in config.php:
	$DeliciousTagometerDefaults = array(
		'size' => 'wide',
		'icon' => 'true',
		'timesSaved' => 'true',
		'graph' => 'true',
		'tags' => 'true'
	);


	For (:deliciousbadge:)
	Users can declare their own network badge using the copy&paste method from http://delicious.com/help/networkbadges via:
	$DeliciousBadgeFmt = 'yourjavascripthere';
	Otherwise, (:deliciousbadge:) can be called with the following arguments:
	* user: delicious.com username (required)
	* icon: medium, small, or none (default: medium)
	* bookmarkcount: true or false (default: true) - number of bookmarks you've collected
	* networkcount: true or false (default: true) - number of networks you belong to
	* fancount: true or false (default: true)- number of fans you have
	* showicon: true or false  (default: true)
	* showname: true or false (default: true) - displays username at the bottom, with a link to user's delicious page

	Declare your own set of default values via $DeliciousBadgeDefaults in config.php:
	$DeliciousBadgeDefaults = array(
		'user' => 'myAccount',
		'icon' => 'medium',
		'bookmarkcount' => 'true',
		'networkcount' => 'true',
		'fancount' => 'true',
		'showicon' => 'true',
		'showname' => 'true'
	);
	
	
    Version Log:

    * March 2006 1.0 - Initial Release
    * January 2007 1.1 - Added tagometer badge
    * November 2008 - Updated for change from delicious.com to delicious.com
    * April 2009 - Bug fixes. changed "label" to "title" to match delicious.com
    * 2009-10-03 - re-uploaded supposed version of April 2009 (just guessing), as it appears November 2008 was what was still being offered above; fixed issue with 'title' not displaying; plus, added $DeliciousBookmarkDefaults and $DeliciousTagDefaults as SDVA's, for easy config.php declaration
    * 2009-10-04 - can now display notes via shownotes=true, plus added showname & showadd; revised (:deliciousbadge:) to permit arguments
    * 2009-10-05 - added more arguments (showadd, showicon, showname) to (:tagroll:). changed (:deliciousbadge:) to incorporate the Delicious Network Badge. The Tagometer is now called via (:tagometer:) and has various arguments. renamed various variable names, and cleaned up the code a bit...
    * 2009-10-14 - added style=none for tagrolls - removes default delicious formatting, allows tagrolls to be formatted via align=right, etc...
