+xR - xC relay protocol analyzer
+
+Synopsis
+--------
+*xR* [_OPTION_]... RELAY-ADDRESS...
+
+Description
+-----------
+*xR* connects to an *xC* relay and prints all incoming events one per line
+in JSON format.  The JSON objects have two additional fields:
+
+when::
+	The time of reception (or sending) as a nanosecond precision
+	RFC 3339 UTC timestamp.
+raw::
+	The incoming event (or outgoing command) in raw binary form.
+
+Options
+-------
+*-debug*::
+	Print any outgoing commands as well, which may help in debugging any issues.
+
+*-version*::
+	Output version information and exit.

Přemysl Eric Janouch	7ba17a0161	Make the relay acknowledge all received commands All checks were successful Alpine 3.21 Success Details Arch Linux AUR Success Details OpenBSD 7.6 Success Details To that effect, bump liberty and the xC relay protocol version. Relay events have been reordered to improve forward compatibility. Also prevent use-after-free when serialization fails. xP now slightly throttles activity notifications, and indicates when there are unacknowledged commands.	2025-05-10 12:08:51 +02:00
