-options are not supported in SVr4 curses.
-.PP
-SVr4 infocmp does not distinguish between absent and cancelled capabilities.
-Also, it shows missing integer capabilities as \fB\-1\fP
-(the internal value used to represent missing integers).
-This implementation shows those as \*(``NULL\*('',
-for consistency with missing strings.
-.PP
-The \fB\-r\fR option's notion of \*(``termcap\*('' capabilities
-is System V Release 4's.
-Actual BSD curses versions will have a more restricted set.
-To see only the
-4.4BSD set, use \fB\-r\fR \fB\-RBSD\fR.
