+# During the transition of CI associated with the repo split,
+# we want all.sh from the mbedtls repo to transparently run both
+# mbedtls and tf-psa-crypto components.
+# This is what this wrapper is about.
+# Once the transition is over, this wrapper can be removed,
+# and mbedtls-all.sh renamed again to all.sh.
+#
+# This wrapper is mostly for the CI's benefit. Developers probably want to
+# directly invoke one or two of the following commands:
+# - tests/scripts/mbedtls-all.sh ...
+# - (cd tf-psa-crypto && tests/scripts/all.sh ...)
 
 # This script must be invoked from the project's root.
