The end result of the Texinfo export process is the creation of an Info file. This Info file’s metadata has variables for category, title, and description: ‘TEXINFO_DIR_CATEGORY’, ‘TEXINFO_DIR_NAME’, and ‘TEXINFO_DIR_DESC’ keywords that establish where in the Info hierarchy the file fits.
Here is an example that writes to the Info directory file:
#+TEXINFO_DIR_CATEGORY: Emacs #+TEXINFO_DIR_NAME: Org Mode #+TEXINFO_DIR_DESC: Outline-based notes management and organizer
