# Upstream distributes HandBrake with bundle of according versions of libraries
# and patches to them. This derivation patches HandBrake to use Nix closure
# dependencies.
#
# NOTE: 2019-07-19: This derivation does not currently support the native macOS
# GUI--it produces the "HandbrakeCLI" CLI version only. In the future it would
# be nice to add the native GUI (and/or the GTK GUI) as an option too, but that
# requires invoking the Xcode build system, which is non-trivial for now.
