+	* codegen binary: no
+	* Makefile snippet: no
 	* codegen-stubhead.hxx
+- get rid of codegen-stubhead.hxx or include a "copy" in each project
+- makefile snippet must work for builds outside of libt2n
+  (=> some variables must be set by configure, the snippet must be installed
+   => pc file template must be installed, too)
