#!/bin/bash

# docs get auto-committed only in our own repo (no forks), only in one of the build environments (to avoid duplicate pushes),
# not on pull requests and only for builds in the master (gitflow = releases) branch and also for tags.
#
# with helpful help from http://benlimmer.com/2013/12/26/automatically-publish-javadoc-to-gh-pages-with-travis-ci/
# and https://github.com/mapnik/node-mapnik/blob/master/scripts/validate_tag.sh

# to be called as "after_success: - ./push-docs-to-gh-pages.sh" in .travis.yml
