# parabola changes and rationale:
# - blacklist rescue for webengine clients which support webkit
# - pin to strongly-coupled dependency versions

# NOTE: for each qt5-base N.N.N release, build order:
#         (qt5-base-N.N.N) <- qt5-webkit <- python-pyqt5 <- qutebrowser
#                                        <- qt5-styleplugins

# TODO: the licensing of 'qt5-webkit' is not clear  (needs review)
#       the AUR 'qt5-webkit' PKGBUILD has not yet migrated to SPDX
#       LGPL-2.1-only is only a guess - there is a LGPL2.1 file in the root dir;
#       but is not obvious which or if any files are covered by it
#       at least one license is not accounted for
#       (the BSD-like license from apple in many files)
