# NOTE: this script originally accepted an 'install' option to munge makepkg.conf in place
# by the libretools.install hooks
# that behavior was replaced by the runtime script: /etc/makepkg.d/librefetch.conf
# (source: libretools::src/librefetch/makepkg-librefetch.conf.in),
# which must be sourced by makepkg.conf in order to enable mksource() handling
# (see `man librefetch`)
#
# note that this is not the 'librefetch.conf' sourced by librefetch and librestage
# (see `man 5 librefetch.conf`)
# that one is: /etc/libretools.d/librefetch.conf
# (source: libretools::src/librefetch/librefetch.conf)
# TODO: one of those should be renamed, to avoid the name collision/confusion
