| 5 | The Ncurses package contains the ncurses, panel, menu and form
|
|---|
| 6 | libraries. It also contains the tic, infocmp, clear, tput, toe and tset
|
|---|
| 7 | programs.

| 16 | <para>
|
|---|
| 17 | The libraries that make up the Ncurses library are used to display text
|
|---|
| 18 | (often in a fancy way) on the screen. An example where ncurses is used
|
|---|
| 19 | is in the kernel's <quote>make menuconfig</quote> process. The libraries
|
|---|
| 20 | contain routines to create panels, menu's, form and general text display
|
|---|
| 21 | routines.

| 29 | Tic is the terminfo entry-description compiler. The program translates a
|
|---|
| 30 | terminfo file from source format into the binary format for use with the
|
|---|
| 31 | ncurses library routines. Terminfo files contain information about the
|
|---|
| 32 | capabilities of a terminal.

| 39 | <para>
|
|---|
| 40 | The infocmp program can be used to compare a binary terminfo entry with
|
|---|
| 41 | other
|
|---|
| 42 | terminfo entries, rewrite a terminfo description to take advantage of
|
|---|
| 43 | the
|
|---|
| 44 | use= terminfo field, or print out a terminfo description from the
|
|---|
| 45 | binary
|
|---|
| 46 | file (term) in a variety of formats (the opposite of what tic does).

|

| 54 | The clear program clears the screen if this is possible. It looks in
|

| 55 | the environment for the terminal type and then in the terminfo database
|
|---|
| 56 | to
|
|---|
| 57 | figure out how to clear the screen.

|

| 65 | The tput program uses the terminfo database to make the values of
|
|---|
| 66 | terminal-dependent capabilities and information available to the shell,
|
|---|
| 67 | to
|
|---|
| 68 | initialize or reset the terminal, or return the long name of the

| 69 | requested
|

| 88 | widely used anymore. It's provided for 4.4BSD compatibility.
