Minetest keeps and looks for files mostly in two paths. `path_share` or `path_user`.
`path_share` contains possibly read-only content for the engine (incl. games and mods).
`path_user` contains mods or games installed by the user but also the users
worlds or settings.
With a local build (`RUN_IN_PLACE=1`) `path_share` and `path_user` both point to
the build directory. For system-wide builds on Linux the share path is usually at
`/usr/share/minetest` while the user path resides in `.minetest` in the home directory.
Paths on other operating systems will differ.
