Sawmill is highly configurable. Global options are stored in the preferences; options specific to a particular profile are stored in each profile file. For a full list of available options, see All Options.
Each profile has its own set of options which controls what that profile does; it specifies the location of the log data, the log format, the database parameters, the reports to display, and more. A profile's options can be changed from the web browser interface using simple graphical forms and controls.
