 # This script expects the following environment variables to be set.  Xcode
 # normally sets them:
 #
 # CONFIGURATION - Release or Debug; this script only operates when Release.
 # SRCROOT - /path/to/chrome/src/chrome
 # BUILT_PRODUTS_DIR - /path/to/chrome/src/xcodebuild/Release
 #
 # The script also takes a single argument defining the branding type.

 # To test this script without running an entire build:
 #
 # cd /path/to/chrome/src/chrome
 # CONFIGURATION=Release \
 #     SRCROOT=$(pwd) \
 #     BUILT_PRODUCTS_DIR=$(pwd)/../xcodebuild/Release \
-#     ../build/mac/dump_app_syms Chromium
