-- A short (one-line) description of the package.
synopsis:           Text layout engine built on top of HarfBuzz.

-- A longer description of the package.
description:
    .
    Given an input text and formatting options, Balkón produces an inline
    layout with defined glyph positions and box coordinates, all within a
    containing unit called a paragraph.
    .
    Internally, HarfBuzz is used to shape individual runs of text, each of
    which fits within one line and has a constant script, direction, language,
    and formatting. Balkón abstracts this so that you can provide text with any
    mix of these attributes and a desired line width for line breaking.
