.br
.SH DESCRIPTION
\fB@CLEAR@\fR clears your screen if this is possible,

and later \fBcat\fP the file to the screen, clearing it at that point.
+.SH OPTIONS
.PP

+.TP 5
+.B \-T \fItype\fP
+indicates the \fItype\fR of terminal.
+Normally this option is
+unnecessary, because the default is taken from the environment
+variable \fBTERM\fR.

+variables \fBLINES\fR and \fBCOLUMNS\fR will also be ignored.
+.TP
+.B \-V
+reports the version of ncurses which was used in this program, and exits.
+The options are as follows:
+.TP
+.B \-x
+do not attempt to clear the terminal's scrollback buffer
