* PORTABILITY:
* SVID 3 - fully
* POSIX.2a UPE - needs clarification between SVID 3 exit statues.
* In particular exit 1 and 4 for string capnames.
* not in XPG 3
*
* SYNOPSIS:
* tput [-T<term>] capname [parm1..parm9]
* tput [-T<term>] -S
*
* DESCRIPTION:
* tput lets you change your terminal's characteristics. The capname
* argument indicates how you want to change the characteristics.
* Some special capnames are:
*
* clear clear the screen
* init initialize terminal in an implemenation-defined way
* reset reset terminal in an implemenation-defined way
* longname print the full name of the ternminal (SVID)
*
* Other capnames are supported and may take from 0 to 9 parameters. A
* list of them can be found in the SVID 3, vol 3. (SVID)
*
* tput does its work by outputting approriate character sequences to the
* standard output. These character sequences are terminal-specific. If
* you specify -T <type>, tput assumes that your terminal has the
* specified type and will issue sequences appropriate to that terminal.
*
* If you do not specify -T, tput looks for an environment variable
* named TERM. If TERM exists, its value is assumed to give the terminal
* type. If TERM does not exist, tput assumes a default terminal type.
*
* The -S option allows more than one capability per invocation of tput.
* The capabilities must be passed to tput from the standard input instead
* of the comamnd line. Only one capname is allowed per line.
*
* EXIT STATUS
* tput may return the following status values:
*
* 0 Either a boolean capname is set true or a string capname was
* successfully written to the terminal.
*
* 1 No error message is printed. Returned if a boolean capname is
* false or a string capname is not defined for the terminal.(SVID)
*
* 2 Usage error.
*
* 3 Unknown terminal <term> or no terminfo database.
*
* 4 Unknown terminfo capability <capname>.
*
* >4 An error occured.
*
*
* NOTE 1: If the Caps file that describes the terminfo database changes
*
* NOTE 2: tput has knowledge about the TERMINAL structure.
