# I need to have a serious conversation with upstream.
# * The main consumer of this package is dev-lang/julia.
# * If I patch gr to install in standard locations, julia does
# not find it anymore.
# * I can't patch julia, since the corresponding scripts are
# downloaded at runtime from its package registry ...
