define Package/plymouth-plugin-ucode/description
  A plymouth splash plugin that hands the screen to a ucode script. The
  script draws with plutovg and decides what changed, so a theme is a
  program rather than a sequence of rendered frames, and it can react to
  ubus events while the system boots.
