Hi Eric

I have written a small patch for the Busybox syslogd. With this patch
one can limit the size of the messagfile. As soon as the limit is
reached the syslogd can rotate or purge the messagefile(s) on his own.
There is no necessity to use an external rotatescript.

Even if logread does something similar, its very handy to have some
messagefile after your box crash.

I wrote this patch initial vor BB 0.6x where no cron daemon was avail.
Now I adapted it for the new Version and i hope it is still useful. At
least I still use it :-)

bye
Arnd
