+======Administering Evergreen Logs======
+Particularly if you have set debugging to a highly verbose level, like ''INFO'' or ''DEBUG'', the Evergreen logs can quickly take up a significant amount of disk space. Fortunately, this is not a new problem for Unix administrators, and there are a number of ways of keeping your logs under control. On Debian and Ubuntu, for example, the ''logrotate'' utility controls when old log files are compressed and a new log file is started. ''logrotate'' runs once a day and checks all log files that it knows about to see if a threshold of time or size has been reached and rotates the log files if a threshold condition has been met.
+To teach ''logrotate'' to rotate Evergreen logs on a weekly basis, or if they are > 50MB in size, create a new file ''/etc/logrotate.d/evergreen'' with the following contents:
+<code>
+compress
+/openils/var/log/*.log {
+  # keep the last 4 archived log files along with the current log file
+  #   log log.1.gz log.2.gz log.3.gz log.4.gz
+  # and delete the oldest log file (what would have been log.5.gz)
+  rotate 5
+  # if the log file is > 50MB in size, rotate it immediately
+  size 50M
+  # for those logs that don't grow fast, rotate them weekly anyway
+  weekly
+}</code>
