A script that I submitted some time ago needed editing to provide DB 
password etc, and Raymond Wagner suggested using mysql.txt instead. Now 
that mysql.txt is deprecated - or worse - it's not obvious to me how I 
ought to use config.xml to get the same result;  maybe browsing around 
other scripts would help, but can I ask here?
