 # Build configs
 
-This directory includes configuration files (json) for the tasks/build.js
-build script.
-
-Notes:
-
-`use_types_for_optimization` is set to `false` for the SIMPLE and WHITESPACE
-builds.  If it was set to `true` we would get function names like
-`ol_control_Control_prototype$setMap` in the compiled code when using the
-SIMPLE compilation. `use_types_for_optimization` is only appropriate for
-ADVANCED compilation. To be sure we also don't set it for WHITESPACE.
