Hello all, The noweb reference in the included file is not present in tangle (and sometimes also is not present within the results in the buffer). I am using: Org-mode version 8.3beta release_8.3beta-625-g8985b3 Please see the attached ECM with my comments (look for BUG). Let me know if you want to have a look to the generated files. You need ledger, but I guess this is a more general problem. Thanks in advance, Daniele
