-Many useful commands are in two `Taskfile.yml` files: [Taskfile.yml](https://github.com/cowork-ai/go-minimp3/blob/main/Taskfile.yml) and [examples/Taskfile.yml](https://github.com/cowork-ai/go-minimp3/blob/main/examples/Taskfile.yml). The format is from [go-task/task](https://github.com/go-task/task), which is similar to [GNU Make](https://www.gnu.org/software/make/).
