91:
92: =over
93:
94: =item prep_menuitems(\@menuitem)
95:

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

105:
106: =item secondary_menu()
107:
108: Same as primary_menu() but operates on @secondary_menu.

121: =item clear()
122:
123: =item switch()
124:
125: Switch a button or create a link
