43: =head1 GLOBAL VARIABLES
44:
45: =over
46:
47: =item @desklines
48:
49: Each element of this array contains a line of mydesk.tab that doesn't start with
50: cat, prim or scnd.
51: It gets filled in the BEGIN block of this module.
52:
53: =item %category_names
54:
55: The keys of this hash are the abbreviations used in mydesk.tab in those lines that
56: start with cat, the values are strings representing titles.

58:
59: =item %category_members
60:
61: TODO
62:
63: =item %category_positions
64:
65: The keys of this hash are the abbreviations used in mydesk.tab in those lines that
66: start with cat, its values are position vectors (column, row).
67: It gets filled in the BEGIN block of this module.
68:
69: =item $readdesk
70:
71: Indicates that mydesk.tab has been read.
72: It is set to 'done' in the BEGIN block of this module.
73:
74: =item @primary_menu
75:
76: The elements of this array reference arrays that are made up of the components
77: of those lines of mydesk.tab that start with prim.
78: It is used by primary_menu() to generate the corresponding menu.
79: It gets filled in the BEGIN block of this module.
80:
81: =item @secondary_menu
82:
83: The elements of this array reference arrays that are made up of the components

91:
92: =over
93:
94: =item prep_menuitems(\@menuitem)
95:
96: This routine wraps a menuitem in proper HTML. It is used by primary_menu() and
97: secondary_menu().
98:
99: =item primary_menu()
100:
101: This routine evaluates @primary_menu and returns XHTML for the menu
102: that contains following links: About, Message, Roles, Help, Logout
103: @primary_menu is filled within the BEGIN block of this module with
104: entries from mydesk.tab
105:
106: =item secondary_menu()
107:
108: Same as primary_menu() but operates on @secondary_menu.
109:
110: =item innerregister()
111:
112: This gets called in order to register a URL in the body of the document
113:
114: =item clear()
115:
116: =item switch()
117:
118: Switch a button or create a link
119: Switch acts on the javascript that is executed when a button is clicked.
120: The javascript is usually similar to "go('/adm/roles')" or "cstrgo(..)".
