Using it

This is built with browserify. If you want a standalone javascript file or UMD module, download leaflet-terminator.js.

If you want to use it with browserify, use npm.

If you have a patch to contribute, change things in index.js or in one of the dependency files. leaflet-terminator.js is a built file, do not change it: your changes will be overwritten.
