%description
node-tracker compares a Bitcoin node's block height with independent views
of the chain (mempool.space, blockstream.info or other nodes) and sends a
Telegram message when the node falls behind, and another when it catches up.
Alerts are debounced and queued until they are delivered.

It runs as a daemon, from a systemd timer or cron, or by hand. The package
ships systemd system and user units and creates the node-tracker system
user; no unit is enabled or started.
