Dune, as a package, is primarily an executable, but its source tree embeds a few public libraries. These are developed in :file:`otherlibs/`.
Some of these have a special link to Dune, such as dune-build-info or
dune-site. Others are just helper libraries that we develop as part of
Dune, but they have a strong relation to the Dune internals, like dyn or
xdg.
