Hi Achilleas,

I'd rather not add additional complexity to the howto Makefile.am.
Most folks have trouble enough understanding what's going on without
adding support for machine generated code.

If I were to add it, I'd do it *exactly* as it is done in

Redirecting your question, is there something in particular that you
don't understand about src/lib/{general,filter}/Makefile.am?

This is the actual make rule that runs the code generator:

        PYTHONPATH=$(top_srcdir)/src/python srcdir=$(srcdir) 

It says that all the generated .h, .i and .cc files are dependent on
everything in $(CODE_GENERATOR), and that if anything in
$(CODE_GENERATOR) is newer than the stuff to the left of the colon, run
generate_all.py to update (generate) them.

CODE_GENERATOR is a list of files that includes the "template files"
*.t, and the code generating scripts themselves generate_*.py.

Did this help?
