at the moment we use the second solution
-- perhaps generate header containing only declarations of server functions
- (hmm this conflicts with the current include file handling)
+- make distcheck
+- .pc file
+- make install (in this example the "other" client lib would have to install foo.hxx)
+- test using valgrind
+
+- would be nice to reduce amount of changed files
+ (codegen output is often the same as the existing files - something similar to ccache
+ for codegen - but not overwriting output files if they are the same)
