     Task is a task runner / build tool that aims to be simpler and easier to use than, for example, <a href="https://www.gnu.org/software/make/">GNU Make<a>.

+    Taskfiles can be written in YAML or HCL. By default Task looks for <code>Taskfile.yml</code>, <code>Taskfile.yaml</code>, <code>Taskfile.hcl</code>, or a plain <code>Taskfile</code> in your project.
