# WARNING: the obvious solution of using || for PyQt5/pyside2 is not going
# to work. The package only checks whether PyQt5/pyside2 is installed, it does
# not verify whether they have the necessary modules (i.e. satisfy the USE dep).
#
# Webengine is a special case, because PyQt6 provides this in a separate package
# while PySide6 ships it in the same package.
