"""Lays a whole English novel out and writes it as one PDF.

The Python twin of the `write_book` example in Rust.

It is what a document's weight really looks like. A novel draws the whole
alphabet in both cases, the digits and the punctuation, so the embedded font
carries far more outlines than an invoice does -- and its metrics, which used to
be stated for every glyph of the face, are stated only for the glyphs the book
draws.

Usage: python examples/write_book.py [out.pdf] [font.ttf]
