  control, or read from terminals via the CLI, or run and interact
  with GUI applications. Covers starting PTYs, sending keystrokes, reading
  output, checking exit status, managing terminal lifecycle, and driving

# blit CLI

blit is a terminal multiplexer and experimental headless Wayland compositor. Every terminal can run both CLI programs (via PTYs) and GUI applications (via the built-in compositor). Surfaces are video-encoded and streamed to browsers; the CLI gives programmatic control over both terminals and graphical windows.

## Install
