The ncurses (new curses) library is a freeware emulation of System V
Release 4.0 curses. It uses terminfo format, supports pads and color
and multiple highlights and forms characters and function-key mapping,
-and has all the other SYSV-curses enhancements over BSD curses.
<P>
+and has all the other SYSV-curses enhancements over BSD curses.<P>
In mid-June 1995, the maintainer of 4.4BSD curses declared that he
considered 4.4BSD curses obsolete, and is encouraging the keepers of
Unix releases such as BSD/OS, freeBSD and netBSD to switch over to
+ncurses.<P>
The ncurses code was developed under Linux. It should port easily to
-any ANSI/POSIX-conforming UNIX. It has even been ported to OS/2 Warp!

The distribution includes the library and support utilities, including a

and a termcap conversion tool captoinfo(1). Full manual pages are provided for

+The ncurses package also has many useful extensions over SVr4:<P>
<UL>
<LI>The API is 8-bit clean and base-level conformant with the X/OPEN curses
but not all EXTENDED features). Most EXTENDED-level features not directly
concerned with wide-character support are implemented, including many
function calls not supported under SVr4 curses (but portability of all
-calls is documented so you can use the SVr4 subset only). <P>

+calls is documented so you can use the SVr4 subset only).
<LI>Unlike SVr4 curses, ncurses can write to the rightmost-bottommost corner

+0-32 through the highlight A_ALTCHARSET.
+<LI>Ada95 and C++ bindings.
+<LI>Support for mouse event reporting under xterm.
+<LI>Extended mouse support via Alessandro Rubini's gpm package.
<LI>The function <CODE>wresize()</CODE> allows you to resize windows, preserving
their data.
-
+<LI>The function <CODE>use_default_colors()</CODE> allows you to
+use the terminal's default colors for the default color pair,
+achieving the effect of transparent colors.
+<LI>The functions <CODE>keyok()</CODE>
+and <CODE>define_key()</CODE> allow
+you to better control the use of function keys,
+e.g., disabling the ncurses KEY_MOUSE,
+or by defining more than one control sequence to map to a given key code.
+<LI>Support for 16-color terminals, such as aixterm and XFree86 xterm.
<LI>Better cursor-movement optimization. The package now features a
cursor-local-movement computation more efficient than either BSD's
-or System V's. <P>
-
+or System V's.
<LI>Super hardware scrolling support. The screen-update code incorporates
a novel, simple, and cheap algorithm that enables it to make optimal
use of hardware scrolling, line-insertion, and line-deletion
for screen-line movements. This algorithm is more powerful than
-the 4.4BSD curses quickch() routine. <P>
-
+the 4.4BSD curses quickch() routine.
<LI>Real support for terminals with the magic-cookie glitch. The
screen-update code will refrain from drawing a highlight if the magic-
cookie unattributed spaces required just before the beginning and
automatically shift highlight boundaries when doing so would make it
possible to draw the highlight without changing the visual appearance
of the screen.
-
<LI>It is possible to generate the library with a list of pre-loaded
fallback entries linked to it so that it can serve those terminal types even
when no terminfo tree or termcap file is accessible (this may be useful
-for support of screen-oriented programs that must run in single-user mode). <P>
-
+for support of screen-oriented programs that must run in single-user mode).
<LI>The tic(1)/captoinfo utility provided with ncurses has the
ability to translate many termcaps from the XENIX, IBM and

+AT&T extension sets.
+<LI>A BSD-like tset(1) utility is provided.
<LI>The ncurses library and utilities will automatically read terminfo
entries from $HOME/.terminfo if it exists, and compile to that directory
if it exists and the user has no write access to the system directory.
This feature makes it easier for users to have personal terminfo entries
-without giving up access to the system terminfo directory. <P>
-
+without giving up access to the system terminfo directory.
<LI>You may specify a path of directories to search for compiled
descriptions with the environment variable TERMINFO_DIRS (this

<LI>In terminfo source files, use capabilities may refer not just to
other entries in the same source file (as in System V) but also to
compiled entries in either the system terminfo directory or the user's
-$HOME/.terminfo directory. <P>
-
+$HOME/.terminfo directory.
<LI>A script (<STRONG>capconvert</STRONG>) is provided to help BSD users
transition from termcap to terminfo. It gathers the information in a
TERMCAP environment variable and/or a ~/.termcap local entries file
-and converts it to an equivalent local terminfo tree under $HOME/.terminfo. <P>
-
+and converts it to an equivalent local terminfo tree under $HOME/.terminfo.
<LI>Automatic fallback to the /etc/termcap file can be compiled in
when it is not possible to build a terminfo tree. This feature is neither
fast nor cheap, you don't want to use it unless you have to,
-but it's there. <P>
