#!/bin/bash

# Script to push output for npm to the `npm` branch of the repository.
# This allows to use the package as a `git` dependency by pointing at this branch
# (or a specific commit).

# Inspired by a similar script in `immutable.js`:
# https://github.com/facebook/immutable-js/blob/master/resources/gitpublish.sh
