 # TODO(mark): https://crbug.com/466890: merge this target with
 # crash_component.
 #
 # This is a temporary base target that is depended on by both
 # crash_component and crash_component_breakpad_mac_to_be_deleted. It
 # provides everything common to both of those targets. For a short period,
 # there are two Mac crash component implementations. The new one uses a
 # Crashpad implementation and is used by Chrome. The old one uses a
 # Breakpad implementation and is used by content_shell. Consumers should
 # depend on the desired target. All three targets behave identically on
