This option will take logs and place them with a time stamp marker in a directory.
/as log ConferenceRoom logfile directory
You will probably want to use this option for any time you are doing reoccuring logging events. Daily, Weekly etc. This way a list of logs and their associated dates and times will be displayed. Much nicer than using one persistant log.
Set the file that the log will ouput to. It will normally place the file within your WEBMASTER\logs directory unless a path is specified.
/as log ConferenceRoom logfile confroom.log
You will probably want to end the file name with either .log or other extension to represent a raw log file.
