Hi I discussed it already with Dan, and he suggested to post the question here: is it possible to have different org files, which then can be combined to a single output (pdf, latex, ...) and, more important, tangled together from a master document? I could imagine something (as suggested by Dan): <> and this code block in the external remote_file would be treated as part of the master-document. So tagling of several external files would be dealt with by tangling the master-document. Thanks, Rainer -- NEW GERMAN FAX NUMBER!!! Rainer M.
