Adding new entries

First make sure the versions of your installed Xcode and Command Line Tools match each other! You can upgrade the Command Line Tools from the tab "Downloads" in the preferences window of Xcode.app.

Then run the following command to generate a new entry and copy it directly to your clipboard for pasting it into this wiki page:
