Thank for your feedback. I don&#x27;t quite understand some of the things you point out as sacrifice. Furthermore:<p>&gt; `setup.py develop`<p>`python __dev__&#x2F;setup.py develop` works correctly<p>&gt; (...) But actually the app is the code, the tests, (...) All are important.<p>`insideout` doesn&#x27;t delete the <i>ugliness</i>. It merely postpones it from the viewer&#x27;s eyes
