This is half a feature request and half a support request. I happily used Zola for my course website this past semester, building via a Github action and publishing to Github pages. The one bump I had was that towards the end of the semester, I made my students a grade calculator (a tiny little react app) and I couldn’t figure out a good way to incorporate that into the Zola build other than a Makefile. I’m curious if people have ideas on how to approach this–it seems like this is fundamentally the same problem faced by people using Tailwind, but I haven’t figured out what their pattern is. It looks like the place to insert a hook of some kind would be [here](https://github.com/getzola/zola/blob/53ce6db057101b8a24631ac4212ab4f9f3d145ae/components/site/src/lib.rs#L685), but “check the config and shell out to run an arbitrary command” doesn’t seem like the best design, else I’d offer to do it. ---

I would use a Makefile for any pre/post processing ---

I did actually find a reference to overriding the `build` command in `config.toml` (I think it was in an example/some blog post, rather than the documentation), but the Makefile approach is working just fine for me at the moment.
