-- configure.in sed s,CODEGEN,XMLPP, oder so
-- one group splitted into multiple .cpp files (=> add support for multiple xml input files)
- remove support for LIBT2N_EXPORT_GROUP(group) (this will simplify the generator a lot)
-- add option similar to gccs -MD
+- 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
+
