# ------------------------------------------------------------------------------
# Note for Developers:
#
# This script sets up the Shrinkwrap environment for local standalone use.
# It is intended for local workflows where you run Shrinkwrap directly,
# outside of `hftest.py`, to build and run Hafnium along with TF-A and TF-A-Test
# projects — particularly when validating SPM-related test suites from TF-A-Test.
#
# If you are running hafnium CI tests via hftest.py, Shrinkwrap is automatically
# configured internally by the test script (hftest.py) — sourcing this script
# is optional.
#
# Usage:
#   source ./../shrinkwrap_setup_env.sh
#   shrinkwrap build ...
#   shrinkwrap run ...
#
# This script ensures the necessary PATH and SHRINKWRAP_* variables are exported
# for use in manual shell workflows.
# Note: Hafnium CI and automation rely on the Python-based setup in
# `ShrinkwrapManager.setup_env()`. If any environment paths or variables change
# here, please update the Python logic accordingly — and vice versa.
