.SS OPTIONS
.TP
\fB\-0\fR
The actual format used incorporates some improvements for escaped characters
from terminfo format.
For a stricter BSD-compatible translation, add the \fB\-K\fR option.
+.IP
+If this is combined with \fB\-c\fR, \fB@TIC@\fR makes additional checks
+to report cases where the terminfo values do not have an exact equivalent
+in termcap form.
+For example:
+.RS
+.bP
+\fBsgr\fP usually will not convert, because termcap lacks the ability to
+work with more than two parameters, and because termcap lacks many of
+the arithmetic/logical operators used in terminfo.
+.bP
+capabilities with more than one delay or with delays before the end of
+the string will not convert completely.
