Rust utility to help find the sources of Google Fonts fonts.
This is currently bare-bones; it inspects (or checks out) the repository at github.com/google/fonts, and for each font parses its metadata file, looking for a repository.
For each repository we find, we then look for a config.yaml file in that
repository's /source directory, which is present by convention on sources
intended to be built by Google Fonts.
To use this tool from the command line, in order to generate a JSON dictionary containing information about source repositories:
cargo run -- -o repo_list.jsonTo use this tool from another Rust crate, see the docs.
