It looks like nginx can do log rotation by sending it USR1, but I haven't seen any English mention of this outside of the source code. Could someone show an example of how log rotation works with nginx? Is there a recommended log rotation tool that can handle this style of log rotation? I've been using piped log processes (mostly rotatelogs) w/ Apache for years to handle this issue.

Currently most of my nginx usage is as a proxy, so I've just turned access logs off.. but I would like to replace Apache in a few other places, so I need to have rotated logs.
