+=head1 NAME
+
+Apache::lonmenu
+
+=head1 SYNOPSIS
+
+Loads contents of /home/httpd/lonTabs/mydesk.tab, 
+used to generate inline menu, and Main Menu page. 
+
+This is part of the LearningOnline Network with CAPA project
+described at http://www.lon-capa.org.
+
+=head1 GLOBAL VARIABLES
+
+=over
+
+=item @desklines
+
+Each element of this array contains a line of mydesk.tab that doesn't start with
+cat, prim or scnd. 
+It gets filled in the BEGIN block of this module.
+
+=item %category_names
+
+The keys of this hash are the abbreviations used in mydesk.tab in those lines that 
+start with cat, the values are strings representing titles. 
+It gets filled in the BEGIN block of this module.
+
+=item %category_members
+
+TODO 
+
+=item %category_positions
+
+The keys of this hash are the abbreviations used in mydesk.tab in those lines that
+start with cat, its values are position vectors (column, row). 
+It gets filled in the BEGIN block of this module.
+
+=item $readdesk
+
+Indicates that mydesk.tab has been read. 
+It is set to 'done' in the BEGIN block of this module.
+
+=item @primary_menu
+
+The elements of this array reference arrays that are made up of the components
+of those lines of mydesk.tab that start with prim:.
+It is used by primary_menu() to generate the corresponding menu.
+It gets filled in the BEGIN block of this module.
+
+=item %primary_sub_menu
+
+The keys of this hash reference are the names of items in the primary_menu array 
+which have sub-menus.  For each key, the corresponding value is a reference to
+an array containing components extracted from lines in mydesk.tab which begin
+with primsub:.
+This hash, which is used by primary_menu to generate sub-menus, is populated in
+the BEGIN block.
+
+=item @secondary_menu
+
+The elements of this array reference arrays that are made up of the components
+of those lines of mydesk.tab that start with scnd.
+It is used by secondary_menu() to generate the corresponding menu.
+It gets filled in the BEGIN block of this module.
+
+=back
+
+=head1 SUBROUTINES
+
+=over
+
+=item prep_menuitems(\@menuitem)
+
+This routine wraps a menuitem in proper HTML. It is used by primary_menu() and 
+secondary_menu().
+
+=item primary_menu()
+
+This routine evaluates @primary_menu and returns a two item array, 
+with the array elements containing XHTML for the left and right sides of 
+the menu that contains the following links: About, Message, Roles, Help, Logout 
+@primary_menu is filled within the BEGIN block of this module with 
+entries from mydesk.tab
+
+=item secondary_menu()
+
+Same as primary_menu() but operates on @secondary_menu.
+
+=item create_submenu()
+
+Creates XHTML for unordered list of sub-menu items which belong to a 
+particular top-level menu item. Uses hover pseudo class in css to display
+dropdown list when mouse hovers over top-level item. Support for IE6 
+(no hover psuedo class) via LC_hoverable class for <li> tag for top-
+level item, which employs jQuery to handle behavior on mouseover.
+
+Inputs: 6 - (a) link and (b) target for anchor href in top level item,
+            (c) title for text wrapped by anchor tag in top level item,
+            (d) reference to array of arrays of sub-menu items,
+            (e) boolean to indicate whether to call &mt() to translate 
+                name of menu item,
+            (f) optional class for <li> element in primary menu, for which
+                sub menu is being generated.
+
+ The underlying datastructure used in (d) contains data from mydesk.tab.
+ It consists of an array which has an array for each item appearing in
+ the menu (e.g. [["link", "title", "condition"]] for a single-item menu).
+ create_submenu() supports also the creation of XHTML for nested dropdown
+ menus represented by unordered lists. This is done by replacing the
+ scalar used for the link with an arrayreference containing the menuitems
+ for the nested menu. This can be done recursively so that the next menu
+ may also contain nested submenus.
+
+ Example:
+ [											# begin of datastructure
+	["/home/", "Home", "condition1"], 		# 1st item of the 1st layer menu
+	[										# 2nd item of the 1st layer menu
+		[									# anon. array for nested menu
+			["/path1", "Path1", undef], 	# 1st item of the 2nd layer menu
+			["/path2", "Path2", undef], 	# 2nd item of the 2nd layer menu
+			[								# 3rd item of the 2nd layer menu
+				[[...], [...], ..., [...]],	# containing another menu layer
+				"Sub-Sub-Menu",				# title for this container
+				undef
+			]
+		],									# end of array/nested menu
+		"Sub-Menu",							# title for the container item
+		undef
+	]										# end of 2nd item of the 1st layer menu
+]
+
+=item innerregister()
+
+This gets called in order to register a URL in the body of the document
+
+=item clear()
+
+=item switch()
+
+Switch a button or create a link
+Switch acts on the javascript that is executed when a button is clicked.  
+The javascript is usually similar to "go('/adm/roles')" or "cstrgo(..)".
+
+=item secondlevel()
+
+=item openmenu()
+
+=item inlinemenu()
+
+=item rawconfig()
+
+=item utilityfunctions()
+
+Output from this routine is a number of javascript functions called by
+items in the inline menu, and in some cases items in the Main Menu page.
