+ A few commands (<STRONG>init</STRONG>, <STRONG>reset</STRONG> and <STRONG>longname</STRONG>) are special;

+ capability names, <STRONG>tput</STRONG> uses several capabilities to per-
+ form these special functions.

<EM>capname</EM>
- indicates the capability from the <STRONG>terminfo</STRONG> data-

AT&T System V provided a different <STRONG>tput</STRONG> command, whose
<STRONG>init</STRONG> and <STRONG>reset</STRONG> subcommands (more than half the program)
were incorporated from the <STRONG>reset</STRONG> feature of BSD <STRONG>tset</STRONG> writ-

- for <EM>reset</EM> was removed from the BSD <STRONG>tset</STRONG> (in June 1993,
- released in 4.4BSD-Lite a year later).
+ ten by Eric Allman.
Keith Bostic replaced the BSD <STRONG>tput</STRONG> command in 1989 with a
new implementation based on the AT&T System V program
Both of these appeared in 4.4BSD, becoming the "modern"
BSD implementation of <STRONG>tput</STRONG>.
+ This implementation of <STRONG>tput</STRONG> began from a different source
+ than AT&T or BSD: Ross Ridge's <EM>mytinfo</EM> package, published
+ on <EM>comp.sources.unix</EM> in December 1992. Ridge's program
+ made more sophisticated use of the terminal capabilities
+ than the BSD program. Eric Raymond used the <STRONG>tput</STRONG> program
+ (and other parts of <EM>mytinfo</EM>) in ncurses in June 1995.
+ Using the portions dealing with terminal capabilities
+ almost without change, Raymond made improvements to the
+ way the command-line parameters were handled.

+ <EM>cap</EM> and <EM>terminfo</EM> names for the <EM>capname</EM> feature, if <EM>termcap</EM>
+ support is compiled in. However, the predefined <EM>termcap</EM>
+ and <EM>terminfo</EM> names have two ambiguities in this case (and
+ the <EM>terminfo</EM> name is assumed):
+
+ <STRONG>o</STRONG> The <EM>termcap</EM> name <STRONG>dl</STRONG> corresponds to the <EM>terminfo</EM> name
+ <STRONG>dl1</STRONG> (delete one line).
+ The <EM>terminfo</EM> name <STRONG>dl</STRONG> corresponds to the <EM>termcap</EM> name
+ <STRONG>DL</STRONG> (delete a given number of lines).
+
+ <STRONG>o</STRONG> The <EM>termcap</EM> name <STRONG>ed</STRONG> corresponds to the <EM>terminfo</EM> name
+ <STRONG>rmdc</STRONG> (end delete mode).
+ The <EM>terminfo</EM> name <STRONG>ed</STRONG> corresponds to the <EM>termcap</EM> name
+ <STRONG>cd</STRONG> (clear to end of screen).

The <STRONG>longname</STRONG> and <STRONG>-S</STRONG> options, and the parameter-substitu-
tion features used in the <STRONG>cup</STRONG> example, were not supported
in BSD curses before 4.3reno (1989) or in AT&T/USL curses
