For new installations:

1. Install the webapp using

   webapp-config -h <VHOST_HOSTNAME> -d <VHOST_APPDIR> -I gallery X.Y.Z

where either the VHOST_HOSTNAME or VHOST_APPDIR are optional and X.Y.Z
is the version of gallery you just emerged.

2. Create a mysql database for Gallery 3.

    mysqladmin -u root -p create gallery3
    mysql gallery3 -u root -p -e \
        "GRANT ALL ON gallery3.* TO username@localhost IDENTIFIED BY 'password'"

3. Now browse to http://<VHOST_HOSTNAME>/<VHOST_APPDIR>/installer.  Make sure
the database name, user and password match what you created in step 2.

4. Enjoy!
