+# This is minimal MicroPython variant of run-tests script, which uses
+# .exp files as generated by run-tests --write-exp. It is useful to run
+# testsuite on systems which have neither CPython3 nor unix shell.
+# This script is intended to be run by the same interpreter executable
+# which is to be tested, so should use minimal language functionality.
