-# This is a transitional wrapper that's only meant for the CI.
-# Developers should directly invoke on or two of:
-# - tests/scripts/mbedtls-all.sh ...
-# - (cd tf-psa-crypto && tests/scripts/all.sh ...)
-#
-# During the transition, it's illegal for a tf-psa-crypto component to have
-# the same name as an mbedtls components; since this wrapper handles both
-# sides at once, component names need to be globally unique. Once the
-# transition period is over, unicity on each side will be enough.
-#
-# For context, here are the steps of the transition:
-# 1. We have an all.sh in tf-psa-crypto but for now we don't invoke it directly
-# on the CI, only through this transitional wrapper in mbedtls. (tf-psa-crypto
-# doesn't have its own CI initially and runs Mbed TLS's instead.)
-# 2. We move all relevant components to tf-psa-crypto so that it gets the level of
-# coverage we want. We need to make sure the new names are unique.
-# 3. We change the CI job on tf-psa-crypto to stop checking out mbedtls and running
-# its all.sh - instead we do the normal thing of checking out tf-psa-crypto and
-# running its all.sh. (In two steps: (a) add the new job, (b) remove the old
-# one.)
-# 4. We remove the transitional wrapper in mbedtls and we're now free to rename
-# tf-psa-crypto components as we want. If we followed a consistent naming
-# pattern, this can be as simple as s/_tf_psa_crypto// in components-*.sh.
+# This file is executable; it is the entry point for users and the CI.
+# See "Files structure" in all-core.sh for other files used.
 
 # This script must be invoked from the project's root.
 
-# There are exactly 4 ways this is invoked in the CI:
-# 1. tests/scripts/all.sh --help
-# 2. tests/scripts/all.sh --list-all-components
-# 3. tests/scripts/all.sh --list-components
-# 4. tests/scripts/all.sh --seed 4 --keep-going single_component_name
-# This wrapper does not support other invocations.
