# NOTICE(slattarini): in an ideal world, we would autonconfiscate the

# populated ones (via ./configure); however, given the current status of
# the build system, compounded by the fact that we use a bundled package
# (SpiderMonkey) which is not autoconfiscated and mostly incompatible with
# several autotools conventions, we take the easier albeit suboptimal
# solution.
