</project>

Starting from the original libphonenumber project and a list of active-countries, this ant project compiles a set of JavaScript executables that can format resp. validate phone numbers from a given country.
Preparation of the single-country metadata is delegated to node.js script slice_country.js.
Compilation creates global object phoneUtils according to Nathan Hammond's libphonenumber porting.
