  BNF-like Syntax of the entries:

  entry ::= entry-line `\n' ( entry )*
  entry-line ::= menu-spec `:' button-type `:' mnemonic `:' action
  menu-spec ::= menu-name ( `>' menu-name )*
  menu-name ::= menu-title `|' accelerator

  menu-title ::= String
  mnemonic ::= <empty> | String
  action ::= <empty> | String
  accelerator ::= `A'|`B'|`C'|...|`a'|`b'|`c'|...
  button-type ::= `PUSH' | `RADIO' | `CHECK' | `SEP'

     - In entry-line, every occurrence of `:' that's not a separator needs to be escaped
       like this: `\:'; similar for `>' in menu-spec and `|' in menu-title.
     - Every `>' in menu-spec creates a submenu for the corresponding menu.
     - mnemonic is the key binding for the action, displayed as mnemonic string in
       the Motif menus (not yet in the Xaw version, since Xaw doesn't provide for
       such mnemonics by default).
     - accelerator is the Motif menu accelerator key.
