+'''
+Generates the `ExternalFontFamily` definitions used in `app/src/font_fallback.rs`.
+These definitions contain the URLs to each external fallback font we use in Warp.
+Generated code is sent to stdout.
+
+This script will read our cloud storage bucket to retrieve the names of the fonts
+we support, and generate the code required to initialize static references for
+each font family.
+
+Assumes that the fallback fonts in the prod `warp-static-assets` bucket are
+identical to the ones stored in the staging `warp-server-staging-static-assets`
+bucket.
+
+Usage:
+1. Make sure the gcloud CLI is installed and you are authed via `gcloud auth login`.
+2. Run `python3 generate_families.py`
+3. Manually inspect the name for each font. The script will generate the name in
+   title-case, but this isn't correct for some fonts (e.g. Noto Sans SC).
