+=head1 NAME
+
+Apache::lonmenu
+
+=head1 SYNOPSIS
+
+Coordinates the response to clicking an image.
+
+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 @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 XHTML for the menu
+that contains 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 show_return_link()
+
+=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(..)".
