# Objective When working within `bevy_ecs`, we can't use the `log_once` macros due to their placement in `bevy_log` - which depends on `bevy_ecs`. All this create does is migrate those macros to the `bevy_utils` crate, while still re-exporting them in `bevy_log`. created to resolve this: https://github.com/bevyengine/bevy/pull/11417#discussion_r1458100211 --------- Co-authored-by: François <mockersf@gmail.com>
