 *** X-symbols are much improved (more symbols, cleaner grammar)
 
 Much more symbols are supported now (C-= C-= for the symbol table).
-Symbols are encoded only if between spaces, ' or _.  Sub/superscripts
-are now introduced by '__' and '^^' respectively, and then the word is
-sub/superscripted until its end.  To put spaces or symbols inside
-sub/superscripts, use _{...} or ^{...}. Notice that this last syntax
-and the ^^ symbol are not understood by Coq and you will need to
-defined it with the "Notation" command of Coq.
-
+See coq/README for the syntax of sub/superscripts.

   Grammar for sub/superscript: 
 
    - a double _ introduces a subscript that ends at the first space
    - a double ^ introduces a superscript that ends at the first space
   
-   - a _ followed by { introduces a subscript
