> DTerm provides an efficient and easy-to-use debugging terminal for
> MacOS 9 and MacOS X programs, and other code.
>
> Here are a few of the features of DTerm:
>
> One version for both Mac OS 9 CFM programs as well as Mac OS X CFM
> and Mach-O programs.
>  Displays results for each program in their own window.
>  Time and date stamps every diagnostic message.
>  Merge the contents of multiple windows into a single window to view
> program interactions.
>  DTerm library has no effect on running applications.
>  Monitoring application can be created to send to end-users.
>
> Yeah, that's great. So how does it work?
>  When the DTerm display application is not running, your program
> will be unaffected by the DTerm library code.
>
> When you want to view the diagnostic or debugging information from
> your programs, simply launch DTerm (or your testers and customers
> can launch the ?mini-DTerm? that you can create from within DTerm),
> and the diagnostic information will be displayed in a separate
> window for each program.
>
> DTerm also time and date stamps every message sent to the monitoring
> app, so that you can not only tell that something happened, but when
> ? and that time and date stamping is automatically done when the
> message is sent to DTerm, not when the message was displayed in the
> window. You can turn the display of the time and date stamp on or
> off, or even display fractional seconds for even more exact timing
> requirements.
