 - 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)
+
+   the variables which must be set:
+       LIBT2N_CODEGEN="\$(top_builddir)/codegen/libt2n-codegen"
+       LIBT2N_CLIENT_PCTEMPLATE="\$(top_srcdir)/codegen/clientlib.pc.in"
+       LIBT2N_CODEGEN_MAKESNIPPET="include \$(top_srcdir)/codegen/codegen.make"
+
+   LIBT2N_CODEGEN will be handled by AC_PATH_PROG
+   the other two? can't we use pkgconfig?!
+   perhaps best provide a m4 macro for use with autoconf?
+   
+       AC_DEFUN([LIBT2N_CODEGEN ...
+
+   alternatively we could add a option --datadir to codegen which prints out the
+   path to clientlib.pc.in and codegen.make
+   (first solution is the better one)
+
+   we can use pkg-config => best solution
+
 - it would really be much nicer if the client lib includes would not depend upon boost serialization
   i thought a solution would be to provide this optionally by wrapping the corresponding includes in a #ifdef
   but this does not work since command.hxx is included which depends on boost serialization headers anyway
   => we do not provide this for now
