+this hook prints absolute filepaths + total size
+
+use this with --xiu, which makes copyparty buffer
+uploads until server is idle, providing file infos
+on stdin (filepaths or json)
+
+example usage as global config:
+    --xiu i1,j,bin/hooks/xiu.py
+
+example usage as a volflag (per-volume config):
+    -v srv/inc:inc:c,xiu=i1,j,bin/hooks/xiu.py
+
+parameters explained,
+    xiu = execute after uploads...
+    i1  = ...after volume has been idle for 1sec
+    j   = provide json instead of filepath list
+
+note the "f" (fork) flag is not set, so this xiu
+will block other xiu hooks while it's running
