#  - drop pandoc makedepend
#  - specify ARM _JARCH's
#  - use zero on ARMv5, adjusted _imgdir
#  - don't build docs, removed docs package; takes a day to build
#  - replace --with-num-cores with --with-jobs
#  - remove --enable-jvm-feature-zgc from configure, not supported on ARM

# TODO add test, see about packaging jtreg and using it here
# TODO see about building with OpenJDK10
# TODO add javazi
# TODO when IcedTea provides it, package icedtea-web and add it as optdepends
# TODO package OpenJFX for OpenJDK10 and add it as optdepends

## EXPLORATIONS
# TODO extract a jmods package from jdk10-openjdk?
# TODO extract a jdk-headless package?
