Well, it is provided as an alternative in this thread (since it will work in many terminals) in case tput does not work as expected, since it is not required by the standards, at least it is only required to support clear, init and reset:

Code:

OPERANDS

The following strings shall be supported as operands by the implementation in the POSIX locale:

clear
      Display the clear-screen sequence.
init
      Display the sequence that initializes the user's terminal in an implementation-defined manner.
reset
      Display the sequence that resets the user's terminal in an implementation-defined manner.

If a terminal does not support any of the operations described by these operands, this shall not be considered an error condition.

tput: operands

so tput is not guaranteed to always produce the right result...

man

MAN(7)							 Miscellaneous Information Manual						    MAN(7)

NAME

       man - macros to typeset manual

SYNOPSIS

       nroff  -man  file ...

       troff  -man  file ...

DESCRIPTION

       These macros are used to lay out pages of this manual.  A skeleton page may be found in the file /usr/man/man0/xx.

       Any  text  argument t may be zero to six words.	Quotes may be used to include blanks in a `word'.  If text is empty, the special treatment
       is applied to the next input line with text to be printed.  In this way .I may be used to italicize a whole line, or .SM followed by .B	to
       make small bold letters.

       A  prevailing  indent  distance	is  remembered	between successive indented paragraphs, and is reset to default value upon reaching a non-
       indented paragraph.  Default units for indents i are ens.

       Type font and size are reset to default values before each paragraph, and after processing font and size setting macros.

       These strings are predefined by -man:

       *R    `(Reg)', trademark symbol in troff.

       *S    Change to default type size.

FILES

       /usr/lib/tmac/tmac.an
       /usr/man/man0/xx

SEE ALSO

       troff(1), man(1)

BUGS

       Relative indents don't nest.
