    (description
     "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}).")

@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

@item Allows you to open the scrollback buffer in a separate window using

simplicity and performance.  With such a strong focus on performance, included
features are carefully considered and you can always expect Alacritty to be
blazingly fast.  By making sane choices for defaults, Alacritty requires no
additional setup.  However, it does allow configuration of many aspects of the
terminal.  Note that you need support for OpenGL 3.2 or higher.")
