This option describes the menu. This is a list whose each five elements describe

{<I>menuname</I> <I>tags</I> <I>menuId</I> <I>tearoff</I> <I>menuentries</I>...}
where <I>menuentries</I> is a list where each element describe one menu entry, which can be:
<UL>
<LI>for a separator:<BR>
  {<B>separator</B>}
<LI>for a command:<BR>
  {<B>command</B> <I>menuname</I> ?<I>tags</I>? ?<I>description</I>? ?<I>accelerator</I>? ?<I>option</I> <I>value</I>? ...}

where:
<UL>
<LI><I>menuname</I> is the name of the menu. If it contains a &amp;, the following character
is automatically converted to the corresponding <B>-underline</B> option of <B>menu add</B>
command.
<LI><I>tags</I> is the tags list for the entry, used for enabling or disabling menu
entries with <B>MainFrame::setmenustate</B>.
<LI><I>menuId</I> is an id for the menu, from which you can get menu pathname with
 <B>MainFrame::getmenu</B>.
<LI><I>tearoff</I> specifies if menu has tearoff entry.
<LI><I>description</I> specifies a string for <A HREF=\"DynamicHelp.html\">DynamicHelp</A>.
<LI><I>accelerator</I> specifies a key sequence. It is a list of two elements, where the first
is one of <B>Ctrl</B>, <B>Alt</B> or <B>CtrlAlt</B>, and the second as letter or a digit.


An accelerator string is build and corresponding binding set on the toplevel to invoke the
menu entry.
<LI><I>option value</I> specifies additionnal options for the entry (see <B>menu add</B>
command).

Each value enclosed by ? are optional and defaulted to empty string, but must be
provided if one or more following options is not empty.
