+# The RouterOS API can neither store multi-line script source (newlines
+# collapse into one line) nor evaluate the [/file/get ...] expression itself.
+# So we fetch the update logic as a .rsc file onto the router's flash, then run
+# a single-line bootstrap script (which the API CAN store) whose body RouterOS
+# evaluates natively: it builds the real, browsable, multi-line named script
+# from the file via [/file get ... contents]. The scheduler then runs that
+# named script by name (the upstream-intended design). The update logic stays
+# out of this repo entirely.
