kannel delivery reports!

Hello,

I have been using stable version of kannel 1.4.3 on a ubuntu machine,So far
only requirement was to send sms's using that kannel but now I need to
configure the delivery report for the messages being sent.



Can anyone help me in the configuration for using delivery reports feature
for kannel.I prefer using php and getting the delivery reports in a flat
file rather then in the mysql / any other database.



Please shed some light on delivery reports for kannel.



Regards,

 ~~RJ
