# The -kN_ and -kaliasLocale keywords are mentioned in the Outside_KDE_repositories wiki.
# We don't need -kN_ since we don't use intltool-extract but might as well keep it.
# I have no idea what -kaliasLocale is used for. Googling aliasLocale found only listed kde1 code.
# We don't need to parse -ki18nd since that'll extract messages from other domains.
