 # TODO(crbug.com/297668): refactor this template to extract common behaviour
 # between OS X and iOS bundle generation, then create a generic "app" template
 # that forward to "executable" on all platform except iOS/OS X.
 
 # Template to build an application bundle for iOS.
 #
 # This should be used instead of "executable" built-in target type on iOS.
 # As the template forward the generation of the application executable to
 # an "executable" target, all arguments supported by "executable" targets
 # are also supported by this template.
