+# depends-pkalgs.pl
+#
+# Copyright (c) 2017, ARM Limited, All Rights Reserved
+#
+# Purpose
+#
+# To test the code dependencies on individual PK algs in each test suite. This
+# is a verification step to ensure we don't ship test suites that do not work
+# for some build options.
+#
+# The process is:
+#       for each possible PK alg
+#           build the library and test suites with that alg disabled
+#           execute the test suites
+#
+# And any test suite with the wrong dependencies will fail.
+#
+# Usage: tests/scripts/depends-pkalgs.pl
+#
+# This script should be executed from the root of the project directory.
+#
+# For best effect, run either with cmake disabled, or cmake enabled in a mode
+# that includes -Werror.
