.SH REMARKS
.PP
The optional argument
.B \-D
specifies that all lines are made with the drawing functions
.B \eD'...'
of
.IR ditroff (1).
This wil make a nicer picture, but creates much more date and is more time
consuming.
Without this argument, some horizontal and vertical lines won't match
nicely.
You're advised not to use this argument at trial runs.
