[erlang-questions] Adding file and line information to erl_syntax trees.

In Zotonic (the Erlang CMS) we are using template_compiler [1] to compile ErlyDTL templates to beam modules.

I would like to include filename and line positions from the original template files in the generated beam code.
This to ease debugging, especially in the case of crashes.

I am a bit at a loss how to best include this information into erl_syntax abstract trees.

Does anybody have an example how to include this information?
