The resulting drawer is a ‘code-details’ and so appears folded;
the user clicks it to see the information therein.
Henceforth, these are called ‘fold drawers’.

Drawers without such a prefix may be nonetheless exported if their
body contains ‘:export: t’ ---this switch does not appear in the output.
Thus, we are biased to generally not exporting non-fold drawers.

One may suspend export of fold drawers by having ‘:export: nil’
in their body definition.

Fold drawers naturally come with a title.

Two options:
- work with =.png= file extension and only replace with =.pdf= when exporting to LaTeX if the corresponding file exists
- work with =.pdf= file, add a special function to display =.pdf= files (using =convert= or =pdftocairo=). Change to =.png= when exporting to html

Let's try the first solution.

* Other
Here are some additional functions/macros that could help you configure Doom:

- `load!' for loading external *.el files relative to this one
- `use-package' for configuring packages
- `after!' for running code after a package has loaded
- `add-load-path!' for adding directories to the `load-path', where Emacs
  looks when you load packages with `require' or `use-package'.
- `map!' for binding new keys

To get information about any of these functions/macros, move the cursor over
the highlighted symbol at press 'K' (non-evil users must press 'C-c g k').
This will open documentation for it, including demos of how they are used.

You can also try 'gd' (or 'C-c g d') to jump to their definition and see how
they are implemented.
