This library is intended to be used to find the plural category of numeric input.

Status
------

Currently produces operands compliant with CLDR 36 into Rust 1.31 and above.

**Updating CLDR Data**

If you would like to update rules.rs with plural rules that are not the specified version above (e.g. future versions of CLDR or external CLDR-compliant rules), you can regenerate the logic in rules.rs with the command:

	cargo regenerate-data

You will need to replace the JSON files under `/cldr_data/` with your new CLDR JSON files.

Local Development
-----------------

    cargo build
    cargo test

When submitting a PR please use  `cargo fmt`.
