title: In psynet, if I use the "newenv" approach, how can I change the psynet code?
body: <p>I want to use the &quot;newenv&quot; approach, but now I need to make changes to psynet (for example adding a log line or rpdb.set_trace()), where is this local copy? And can I simply change it or I need to reinstall the environment with reenv?</p>
