+# Use this script to use interfaces/files from tempest-lib.
+# Many files have been migrated to tempest-lib and tempest has
+# its own copy too.
+# This script helps to remove those from tempest and make use of tempest-lib.
+# It adds the change-id of each file on which they were migrated in lib.
+# This should only be done for files which were migrated to lib with
+# "Migrated" in commit message as done by tempest-lib/tools/migrate_from_tempest.sh script.
+# "Migrated" keyword is used to fetch the migration commit history from lib.
+# To use:
+#  1. Create a new branch in the tempest repo so not to destroy your current
+#     working branch
+#  2. Run the script from the repo dir and specify the file paths relative to
+#     the root tempest dir(only code and unit tests):
+#
+#   tools/use_tempest_lib.sh.sh tempest/file1.py tempest/file2.py
