     "Libptytty is a small C/C++ library to manage pseudo-ttys in a uniform way,
created out of frustration over the many differences of PTY/TTY handling in
different operating systems.

In addition to mere PTY/TTY management, it supports updating the session
database at @file{utmp}, and @file{wtmp}/@file{lastlog} for login shells.

It also supports @code{fork}ing after start-up and dropping privileges in the
calling process.  This reduces the potential attack surface: if the calling
process were to be compromised by the user starting the program, there would be
less to gain, as only the helper process is running with privileges (e.g.,
@code{setuid}/@code{setgid}).")

@itemize
@item Offloads rendering to the GPU for lower system load and buttery smooth
scrolling.  Uses threaded rendering to minimize input latency.
@item Supports all modern terminal features: graphics (images), unicode,
true-color, OpenType ligatures, mouse protocol, focus tracking, bracketed
paste and several new terminal protocol extensions.
@item Supports tiling multiple terminal windows side by side in different
layouts without needing to use an extra program like tmux.
@item Can be controlled from scripts or the shell prompt, even over SSH.
@item Has a framework for Kittens, small terminal programs that can be used to
extend kitty's functionality.  For example, they are used for Unicode input,
hints, and side-by-side diff.
@item Supports startup sessions which allow you to specify the window/tab
layout, working directories and programs to run on startup.
@item Allows you to open the scrollback buffer in a separate window using
arbitrary programs of your choice.  This is useful for browsing the history
comfortably in a pager or editor.
