   8 #
   9 # This script creates additional helper .app bundles for Chromium, based on
  10 # the existing helper .app bundle, changing their Mach-O header's flags to
  11 # enable and disable various features.
  12 #
  13 # This script expects to be called from the chrome_exe target as a postbuild,
  14 # and operates directly within the built-up browser app's versioned directory.
  15 #
  16 # Each helper is adjusted by giving it the proper bundle name, renaming the
  17 # executable, adjusting several Info.plist keys, and changing the executable's
  18 # Mach-O flags.
