-You will need to specify all of these environment variables. :envvar:`WIZARD_WEB_HOST`
-and :envvar:`WIZARD_WEB_PATH` indicate Wizard's configuration with respect to
-your web server. ``http://$WIZARD_WEB_HOST/$WIZARD_WEB_PATH`` will be the location
-that a newly installed application will be accessible. You will notice that
-we used :envvar:`TESTDIR`; this is the directory that will be created in
-:file:`tests` for the application. :envvar:`WIZARD_MYSQL_HOST`,
-:envvar:`WIZARD_MYSQL_USER`, :envvar:`WIZARD_MYSQL_PASSWORD` and :envvar:`WIZARD_MYSQL_DB`
-are standard configuration variables for accessing a local MySQL database. You can use
-:envvar:`TESTID` to uniquely identify any particular test. Finally, :envvar:`WIZARD_EMAIL`
-is any email address you own that will be configured as an administrative email.
-
-It may be useful to include a little bit of code to handle dropping and creating
-databases. Here is a sample::
-
- MYSQL_ARGS="-uroot -prootpassword"
- mysql $MYSQL_ARGS -e "DROP DATABASE \`$WIZARD_MYSQL_DB\`;" || true
- mysql $MYSQL_ARGS -e "CREATE DATABASE \`$WIZARD_MYSQL_DB\`;"
+You will need to specify all of the environment variables in the
+:file:`config`. Those prefixed with ``WIZARD`` are directly used by Wizard,
+while the ``MYSQL`` environment variables are used if a test script wants to
+interactive directly with a MYSQL database. We don't quite have a good story
+for alternative databases in test scripts.
+
+* :envvar:`WIZARD_WEB_HOST` and :envvar:`WIZARD_WEB_PATH` indicate Wizard's
+ configuration with respect to your web server.
+ ``http://$WIZARD_WEB_HOST/$WIZARD_WEB_PATH`` will be the location that a newly
+ installed application will be accessible. You will notice that we used
+ :envvar:`TESTDIR`; this is the directory that will be created in :file:`tests`
+ for the application.
+* :envvar:`WIZARD_DSN` is the database source name, which
+ should be used to access a MySQL database (as Wizard does not contain support
+ for any other database system yet.) You can use :envvar:`TESTID` to uniquely
+ identify any particular test.
+* :envvar:`WIZARD_EMAIL` is any email address you
+ own that will be configured as an administrative email.
