# fontfeatures

Detect a font file’s available [OpenType features](https://www.microsoft.com/typography/otspec/featurelist.htm).

Uses [Fontkit](https://github.com/devongovett/fontkit/) to read font files and spit out basic information. For example, “Does this font support small caps?”

## Install

```bash
npm install -g fontfeatures
```

## Usage

```bash
fontfeatures ApexSerif-Book.woff
```

## Sample Output
