This is a monorepo providing the following npm packages:

• make-plural-compiler - Translates Unicode CLDR pluralization rules to executable JavaScript
• make-plural-cli - Command-line interface for the compiler
• make-plural - Precompiled Unicode CLDR pluralization rules as JavaScript functions

git clone https://github.com/eemeli/make-plural.git
cd make-plural
npm install
npm run build

Note that with the v5 release, the compiler and CLI were split from the canonical make-plural package.
