Warning: Kimwitu V4_3 and newer contain incompatible changes wrt
Kimwitu V4_0 and older.

 - the rewrite_<phylum> functions contain an additional second parameter
   for a (rewrite-) view. The default rewrite-view is 'base_rview'.
   	void rewrite_<phylum>( <phylum> p, rview v );

 - the 'view' type has been 'renamed' to 'uview' (short for Unparse-view),
   the default 'base_view' has been renamed to 'base_uview'.
   the '%view' keyword has been renamed to '%uview'.
   The old names can still be used, but you are encouraged to use the new
   ones.

 - there is an extended syntax for rewrite rules:
	 pattern ->  < view1 view2 view... : term >;
   (or even more general, just like unparse rules:
     pattern1, pattern2, ... -> < views : term >, < views2 : term2 >, ... ;
   )
   and you can declare rewrite views as
   '%rview view1 view2 ...;

In addition, Kimwitu V4_3 and newer contain an incompatible change wrt
Kimwitu V4_2_1. (sorry for this confusion)

 - in V4_2_1 the print_<phylum> functions contain an additional (first)
   parameter (for a file pointer (or 0, for stdout)
   in V4_3 and V4_0 and older, print_<phylum> has only one parameter:
   	void print_<phylum>( <phylum> p );
   V4_3 and newer contain new fprint_<phylum> functions that contain
   two parameters:
   	void fprint_<phylum>( FILE* f, <phylum> p );
