-Use `--subset=*.ttf` to select some font files for subsetting. Note that you can also [subset yourself manually with `pyftsubset`](docs/manual-subset.md) (but glyphhanger is easier).

 Because we’re not parsing URLs for glyphs, we can optionally use `--family='My Family Name'` to set the name used in the `@font-face` block. Normally `--family` would tell GlyphHanger to only parse text data from nodes using one of the fonts listed in `--family`. Using `--subset` and `--css` together will write a CSS file, too.
