 log_title=Logging
 log_desc=Webmin can be configured to write a log of web server hits, in the standard CLF log file format. If logging is enabled, you can also choose whether IP addresses or hostnames are recorded, and how often the log file is cleared. When enabled, logs are written to the file $1.
