Is it possible to extend the built-in dependency tracking?

Hello,

I am looking into how to add a dependency tracking into the build
process of my project.  The project is written in GNU Guile, so it does
not track them out of the box.  GNU Automake has a feature to track
dependencies -- described in (automake)Dependencies -- however I did not
manage to find any documentation on whether it is possible to add user
provided tooling for new languages.

The best I have managed to find is (make)Automatic Prerequisites.  I
will try to use it, however I wonder whether there is some way to
configure Automake to handle most of that for me (assuming I provide a
script to generate the dependency files).

Connected question, can I use the $(DEPDIR) macro in my rules and expect
it to keep working, or -- since it is not documented -- it could be
removed in some future release?

Thank you and have a nice day,
Tomas Volf
