SQLRelay config file
	<?xml version="1.0"?>
	<instances>
	  <instance id="ID" port="PORT" unixport="" dbase="freetds" connections="4" maxconnections="8" maxqueuelength="4" growby="" ttl="60" endofsession="rollback" sessiontimeout="" socket="" runasuser="" runasgroup="" cursors="" authtier="connection">
	    <users>
	      <user user="SQLRELAY-USER" password="SQLRELAY-PASSWORD"/>
	    </users>
	    <connections>
	      <connection connectionid="CONNECTION-ID" string="user=MS-SQL-USER;password=HIS-PASSWORD;server=FREETDS-SERVER-NAME" metric="1"/>
	    </connections>
	  </instance>
	</instances>

Corresponding freetds config file:
	....
	[FREETDS-SERVER-NAME]
		host = MS-SQL-SERVER-NAME-OR-IP
		port = 1433
		tds version = 7.0

Watch out for ALL UPPERCASE names above. You need to adapt them (consistently)
to your needs. When you use an older MS SQL server, your "tds version"
should be "4.2" rather than "7.0".

You will start SQLRelay with "sqlr-start id=ID" ("ID" what you defined above).

You will connect to SQLRelay with the "SQLRELAY-USER" and
"SQLRELAY-PASSWORD" above. SQLRelay in turn will connect to
your SQL server with the "MS-SQL-USER" and "HIS-PASSWORD" above.

There are more options for the connection string than shown above,
e.g. to control language and charset. They are documented
in the configuration section of the SQLRelay documentation.
Documentation is terse but complete...
