CLEANFILES must be listed directly, too - otherwise automake will not use it :-(

[libt2n] / codegen / TODO

- remove support for LIBT2N_EXPORT_GROUP(group) (this will simplify the generator a lot)
- add option similar to gccs -MD (at the moment it is a fixed set of files generated and
  they are handled in the makefile)

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

   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
