my.cnf errors..

[George Thompson]

ok, so ill just say it, im new to mysql.. atleast when it comes to trying to modify it, i've read in places about how to make mysql run more efficiently for different servers, and so i tried to get a new file to use based on the hardware i have, but when i try to resart mysql from Putty, im getting this error..

/etc/init.d/mysql restart
error: Found option without preceding group in config file: /etc/my.cnf at line: 1
Fatal error in defaults handling. Program aborted
