define Package/ripe-atlas/Default/description
  RIPE Atlas is the RIPE NCC's main Internet data
  collection system. It is a global network of
  devices, called probes and anchors, that
  actively measure Internet connectivity. Anyone
  can access this data via Internet traffic maps,
  streaming data visualisations, and an API.
  RIPE Atlas users can also perform customised
  measurements to gain valuable data about their
  own networks.

# The measurement applets need raw sockets. With procd-ujail installed the
# probe runs as ripe-atlas and ujail hands it CAP_NET_RAW from
# capabilities.json; without ujail the init falls back to root, as
# atlas-sw-probe always ran, because procd grants capabilities only via ujail.
