This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
`npm-run-all` is getting complexity step by step. So I experiment to separate it to 2 simple commands -- `run-s` and `run-p`. - `run-s` - Run specific tasks sequentially. - `run-p` - Run specific tasks in parallel. Those commands don't have the ability of combinations of parallel and sequential.
