+/** Help with local development in the webapp/static dir by copying code from server.py.
+*   If a file is added to the server.py lists, it needs to be added here too.
+* 
+* To run on the command line in your running docker container:
+docker exec -it your_docker_container_name /bin/bash
+cd /tmp/docassemble
+node docassemble_webapp/docassemble/webapp/static/app/bundle_webapp.js
+su www-data
+source /usr/share/docassemble/local3.10/bin/activate
+pip install --no-deps --no-index --upgrade --force-reinstall ./docassemble_base ./docassemble_webapp ./docassemble ./docassemble_demo && exit
+supervisorctl start reset
+* 
+* Then wait for the server to restart. You can pip install fewer of those
+*   directories if you know what you're doing.
