# Publishes a new version of the Jsonnet website.

# This script does the following:
#
# 1. Builds an archive containing the Jekyll website
# 2. In a temporary directory or the provided WORKING_DIR, clones the
# Jsonnet website, and checks out the gh-pages branch
# 3. Replaces the contents of the repository with the new version of the site
# from the archive
# 4. Commits the new version of the site and pushes to the remote repository.
#
# Usage:
# push_docs.sh [WORKING_DIR]
