+# Usage: radacct-rotate [options]
+#
+# Compress and later remove old FreeRADIUS' radacct log files with "-YYYYMMDD"
+# suffix. This script is provided by the freeradius package in Alpine Linux.
+#
+# Options:
+#   -C FILE  Location of radacct-rotate config file (defaults to
+#            /etc/raddb/radacct-rotate.conf).
+#
+#   -c DAYS  Compress files older than DAYS (overrides option
+#            compress_after_days from the config).
+#
+#   -r DAYS  Remove compressed files older than DAYS (overrides
+#            option remove_after_days from the config).
+#
+#   -d       Run in dry-run mode (only print what would be done).
+#
+#   -h       Show this message and exit.
