Thanks for fixing!

File tools-webrtc/android/profiling/perf_setup.sh (right):

tools-webrtc/android/profiling/perf_setup.sh:37: SCRIPT_PATH="${(%):-%N}"
I can't say how that works but I trust you :-)

PS, I remember that I've seen this in another script. Looks simpler but not sure
if it resolves the exact same thing:

# Make sure we're being sourced (possibly by another script). Check for bash
# since zsh sets $0 when sourcing.
if [[ -n "$BASH_VERSION" && "${BASH_SOURCE:-$0}" == "$0" ]]; then
  echo "ERROR: envsetup must be sourced."
  exit 1
fi
