between external components such as 'latex', 'ffmpeg', 'gnuplot', 'diagrams',
and 'povray'.

    -- | Reanimate features a web-based viewer which is opened by default if
    --   no other parameters are given. Key features:
    --
    --   * This viewer listens for changes to the source file and recompiles the
    --     code automatically as needed.
    --   * Animations are rendered with increasing fidelity until the frame
    --     rate eaches 60 fps.
    --   * Key commands for pausing, frame stepping, forward/rewind.
    --     To pause press SPACE, to move -1\/+1\/-10\/+10 frames use LEFT\/RIGHT\/DOWN\/UP arrow keys.
