# releases/${MACHINE}/${MACHINE_ARCH}/*-RELEASE/
#     The official FreeBSD releases as individual tarballs to download; useful
#     for jail hosting, updating machines in situ, etc.  Make sure to look in
#     the ${MACHINE_ARCH} sub-directory for the most recent releases (e.g.,
#     releases/amd64/amd64); this is a change from the earlier ${ARCH} naming
#     scheme (e.g., releases/amd64).
#
# snapshots/${MACHINE}/${MACHINE_ARCH}/*-{STABLE,CURRENT}/
#     Intermittently updated snapshots of -CURRENT and selected -STABLE
#     branches.  A good way to seed a development machine or test in-progress
#     FreeBSD features.
