 which is a list of the parameters to be prompted for before a

+*** Added `sql-connection-alist' to record login parameter values.
+An alist for recording different username, database and server
+values.  If there are multiple databases that you connect to the
+parameters needed can be stored in this alist.
+
+For example, the following might be set in the user's init.el:
+
+  (setq sql-connection-alist
+        '((dev (sql-product 'sqlite)
+               (sql-database "/home/mmaug/dev.db"))

+               (sql-database "iprd2a"))))
+
+This defines two connections named "dev" and "prd".
+
+*** Added `sql-connect' to use predefined connections.
+Sets the login parameters based on the values in the
+`sql-connection-alist' and start a SQL interactive session.  Any
+values specified in the connection will not be prompted for.
+
+In the example above, if the user were to invoke M-x sql-connect, they
+would be prompted for the connection.  The user can respond with
+either "dev" or "prd".  The "dev" connection would connect to the
+SQLite database without prompting; the "prd" connection would prompt
+for the users password and then connect to the Oracle database.
+
 *** Added option `sql-send-terminator'.
 When set makes sure that each command sent with `sql-send-*' commands
 are properly terminated and submitted to the SQL processor.
 
 *** Added option `sql-oracle-scan-on'.
 When set commands sent to Oracle's SQL*Plus are scanned for strings
