105: secondary_menu().
106:
107: =item primary_menu()
108:
109: This routine evaluates @primary_menu and returns XHTML for the menu
110: that contains following links: About, Message, Roles, Help, Logout

1.375 raeburn 118: =item create_submenu()
119:
120: Creates XHTML for unordered list of sub-menu items which belong to a

123: (no hover psuedo class) via LC_hoverable class for <li> tag for top-
124: level item, which employs jQuery to handle behavior on mouseover.
125:
126: Inputs: 4 - (a) link and (b) target for anchor href in top level item,
127: (c) title for text wrapped by anchor tag in top level item.
