open questions:
- should projects using the codegen depend on installed version of ... or ship their own version?
- * codegen binary
- * Makefile snippet
+ * 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)
