@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.

     "Alacritty is a GPU-accelerated terminal emulator with a strong focus on
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.")
