TattleTale provides very complete information about your computer and its system related software. The information can be viewed on screen by category, printed, written to a standard text file, or output in database readable format. As such, it also provides a record of your system configuration that can be used for reporting problems to software and hardware manufacturers, to compare configurations across multiple computers, or to simply learn about your machine. Information categories covered are: the CPU, Volumes + Drives, Monitors, Nubus Devices, SCSI Devices, ADB Devices, Serial Ports, General System Attributes, Startup Environment, System Files (System, Finder, INITS, CDEVs, RDEVs etc.), DAs, Fonts, Drivers, Open Files, Processes, and Available/UnAvailable Traps. In addition, it enables you to Mount Volumes and Close Files that were left open. The information provided varies greatly among these categories and is best understood simply by going to the dialog window and browsing through the above categories.
NOTE: The Traps information is valuable for programmers who are always wondering if a particular combination of system software and hardware implements a certain trap.
