Clicking the update button downloads a new 4.0.4, but what do I do next.
This is what I'm thinking of doing: The old executable is in /opt/pycharm-4.0, and I have created a new directory /opt/pycharm-4.0.4. The script for executing pycharm is in /usr/local/zacktu/pycharm. I can change the script's RUN_PATH to point to /opt/pycharm-4.0.4/bin/pycharm.sh. What about CONFIG_FILE? Can I leave CONFIG_FILE to point to /home/zacktu/.PyCharm40/config?
