1 - remove support for LIBT2N_EXPORT_GROUP(group) (this will simplify the generator a lot)
2 - add option similar to gccs -MD (at the moment it is a fixed set of files generated and
3 they are handled in the makefile)
6 - should projects using the codegen depend on installed version of ... or ship their own version?
10 - get rid of codegen-stubhead.hxx or include a "copy" in each project
11 - makefile snippet must work for builds outside of libt2n
12 (=> some variables must be set by configure, the snippet must be installed
13 => pc file template must be installed, too)
14 - it would really be much nicer if the client lib includes would not depend upon boost serialization
15 i thought a solution would be to provide this optionally by wrapping the corresponding includes in a #ifdef
16 but this does not work since command.hxx is included which depends on boost serialization headers anyway
17 => we do not provide this for now
