+‘cppawk’
+     Quoting from the web page, “‘cppawk’ is a tiny shell script that is
+     used like ‘awk’.  It invokes the C preprocessor (GNU ‘cpp’) on the
+     Awk code and calls Awk on the result.” This program may be of use
+     if the way ‘gawk’’s ‘@include’ facility works doesn’t suit your
+     needs.  For more information, see
+     <https://www.kylheku.com/cgit/cppawk/>.
