+ A <STRONG>clear</STRONG> command appeared in 2.79BSD dated February 24,
+ 1979. Later that was provided in Unix 8th edition (1985).
+
+ AT&amp;T adapted a different BSD program (<STRONG>tset</STRONG>) to make a new
+ command (<STRONG>tput</STRONG>), and used this to replace the <STRONG>clear</STRONG> command
+ with a shell script which calls <STRONG>tput</STRONG> <STRONG>clear</STRONG>, e.g.,
+ /usr/bin/tput ${1:+-T$1} clear 2&gt; /dev/null
+ exit
+
+ In 1989, when Keith Bostic revised the BSD <STRONG>tput</STRONG> command to
+ make it similar to the AT&amp;T <STRONG>tput</STRONG>, he added a shell script
+ for the <STRONG>clear</STRONG> command:
+ exec tput clear
+
+ The remainder of the script in each case is a copyright
+ notice.
+
+ The ncurses <STRONG>clear</STRONG> command began in 1995 by adapting the
+ original BSD <STRONG>clear</STRONG> command (with terminfo, of course).
+
+ The <STRONG>E3</STRONG> extension came later:
+
+ <STRONG>o</STRONG> In June 1999, xterm provided an extension to the stan-
+ dard control sequence for clearing the screen. Rather
+ than clearing just the visible part of the screen
+ using
+ printf '\033[2J'
+
+ one could clear the <EM>scrollback</EM> using
+ printf '\033[<STRONG>3</STRONG>J'
+
+ This is documented in <EM>XTerm</EM> <EM>Control</EM> <EM>Sequences</EM> as a
+ feature originating with xterm.
+
+ <STRONG>o</STRONG> A few other terminal developers adopted the feature,
+ e.g., PuTTY in 2006.
+
+ <STRONG>o</STRONG> In April 2011, a Red Hat developer submitted a patch
+ to the Linux kernel, modifying its console driver to
+ do the same thing. The Linux change, part of the 3.0
+ release, did not mention xterm, although it was cited
+ in the Red Hat bug report (#683733) which led to the
+ change.
+
+ <STRONG>o</STRONG> Again, a few other terminal developers adopted the
+ feature. But the next relevant step was a change to
+ the <STRONG>clear</STRONG> program in 2013 to incorporate this exten-
+ sion.
+
+ <STRONG>o</STRONG> In 2013, the <STRONG>E3</STRONG> extension was overlooked in <STRONG>tput</STRONG> with
+ the "clear" parameter. That was addressed in 2016 by
+ reorganizing <STRONG>tput</STRONG> to share its logic with <STRONG>clear</STRONG> and
+ <STRONG>tset</STRONG>.

+ Neither IEEE Std 1003.1/The Open Group Base Specifica-

+ documents tset or reset.
+
+ The latter documents <STRONG>tput</STRONG>, which could be used to replace
+ this utility either via a shell script or by an alias

.SH DESCRIPTION
\fB@CLEAR@\fR clears your screen if this is possible,
-including its scrollback buffer (if the extended "E3" capability is defined).
+including its scrollback buffer (if the extended \*(``E3\*('' capability is defined).
\fB@CLEAR@\fR looks in the environment for the terminal type and then in the
\fBterminfo\fR database to determine how to clear the screen.
.PP
\fB@CLEAR@\fR ignores any command-line parameters that may be present.
+.SH HISTORY
+A \fBclear\fP command appeared in 2.79BSD dated February 24, 1979.
+Later that was provided in Unix 8th edition (1985).
+.PP
+AT&T adapted a different BSD program (\fBtset\fP) to make
+a new command (\fBtput\fP),
+and used this to replace the \fBclear\fP command with a shell script
+which calls \fBtput clear\fP, e.g.,
+.NS
+/usr/bin/tput ${1:+-T$1} clear 2> /dev/null
+exit
+.NE
+.PP
+In 1989, when Keith Bostic revised the BSD \fBtput\fP command
+to make it similar to the AT&T \fBtput\fP,
+he added a shell script for the \fBclear\fP command:
+.NS
+exec tput clear
+.NE
+.PP
+The remainder of the script in each case is a copyright notice.
+.PP
+The ncurses \fBclear\fP command began in 1995 by adapting the original
+BSD \fBclear\fP command (with terminfo, of course).
+.PP
+The \fBE3\fP extension came later:
+.bP
+In June 1999, xterm provided an extension to the standard control
+sequence for clearing the screen.
+Rather than clearing just the visible part of the screen using
+.NS
+printf '\\033[2J'
+.NE
+.IP
+one could clear the \fIscrollback\fP using
+.NS
+printf '\\033[\fB3\fPJ'
+.NE
+.IP
+This is documented in \fIXTerm Control Sequences\fP as a feature originating
+with xterm.
+.bP
+A few other terminal developers adopted the feature, e.g., PuTTY in 2006.
+.bP
+In April 2011, a Red Hat developer submitted a patch to the Linux
+kernel, modifying its console driver to do the same thing.
+The Linux change, part of the 3.0 release, did not mention xterm,
+although it was cited in the Red Hat bug report (#683733)
+which led to the change.
+.bP
+Again, a few other terminal developers adopted the feature. But the
+next relevant step was a change to the \fBclear\fP program in 2013
+to incorporate this extension.
+.bP
+In 2013, the \fBE3\fP extension was overlooked in \fB@TPUT@\fP with
+the \*(``clear\*('' parameter.
+That was addressed in 2016 by reorganizing \fB@TPUT@\fP to share
+its logic with \fB@CLEAR@\fP and \fB@TSET@\fP.
+.SH PORTABILITY
+Neither IEEE Std 1003.1/The Open Group Base Specifications Issue 7
+(POSIX.1-2008) nor X/Open Curses Issue 7 documents @TSET@ or @RESET@.
+.PP
+The latter documents \fBtput\fP, which could be used to replace this utility
+either via a shell script or by an alias (such as a symbolic link) to
+run \fB@TPUT@\fP as \fB@CLEAR@\fP.
