The program will tell you to go to https://gerrit.libreoffice.org and sign in to automatically provision your account from our Single Single-On system. The program will also generate a key pair for SSH and print the public part (that is, the content of
/home/[username]/.ssh/id_rsa.pub). This is a long random-looking string beginning with 'ssh-rsa'. You must add it to your settings page for gerrit to work from the command line.
