[Opensim-users] configuring the log files

I like the idea of the rotating log file and have just added it to my sim.

Earlier I changed:

to

This gives a less verbose, but still gives the essential information for normal operation.

I would certainly suggest this for a default setup. It is easy enough to change if there is a problem.
