# * prefetch the videojs dependencies with scripts/fetch-player-dependencies.cr
# and update .videojs.hash (they are normally fetched during build
# but nix's sandboxing does not allow that)
# * if shard.lock changed
# * recreate shards.nix by running crystal2nix
# * update lsquic and boringssl if necessarry, lsquic.cr depends on
# the same version of lsquic and lsquic requires the boringssl
# commit mentioned in its README
