According to [this comment in pwr project](https://github.com/jesusprubio/pwr/pull/11#issuecomment-478125434) I'd like to finish and move [code](https://github.com/jesusprubio/pwr/pull/11/files) here. Before that I'd like to ask if I can count on a relatively fast merge, because this project has not been changed for a long time.
