[syslog-ng]weekly directory

Hi guys, is there any way to create a directory for each week?? We can do it by day/month/year but for some host month is too big and day is too small, so can we do something between ? Thanx a lot and have a nice day! Kéven Belanger Analyste en solutions de sécurité Logicon Inc. - Division Sécurité 819.825.8049 x7717 800.567.6399 x7717
