# NOTE: building this documentation is a pain in the ass. Dependencies are not pinned, but
# even when pinned there are still more errors and exceptions. Plus, during the build
# they seem to be downloading some datasets over HTTP that are no longer availabe (error 404).
# Building older versions is basically impossible  (┛ಠ_ಠ)┛彡┻━┻

# requires to have fortran, meson, libopenblas, graphviz, pandoc installed
