* On the VMS and unix, this option controls whether a delay is done by

* on MSDOS (without the termcap routines) is used to determine whether to
* include the delay routines in the code (and thus, provides a compile time
* method to turn off napping for visual effect).  However, it is also used
* in the music code to wait between different notes.  So it is needed in that
* case as well.

* Whereas on the VMS and unix, flags.nap is a run-time option controlling
* whether there is a delay by clock or by excess output, on MSDOS it is
* simply a flag to turn on or off napping for visual effects at run-time.
