Script to rotate virtual-server logs Apache2

[Account for Debian group mail <debian@pcez.com>]

Hello,

I the Apache 1.3 servers there was a way to rotate logs in the log
directories for each of the virtual servers. I could not find a way to do
this in the New Apache2 server. So I hacked up the old apache cron script
and put this into the /etc/cron.weekly/ directory and it seems to do the
trick now.

I thought I would post that script here for anyone that wants to use it.
Do as you like to it, if you make any improvements to it please post it
here.

Thanks,

Ken

# This next command will read the links in the /etc/apache2/sites-enabled directory
# I made it so my links are domain names so it will not read the "000-default" link
# but will read a link "somedomain.com" This is because the rotate "logrotate.d/apache"
# script already takes care of this default directory.
