#!/bin/bash

# Usage: ./build overview-server.zip (also builds overview-server.tar.gz)
#
# (If invoked from your shell, it will run in a new Docker container.)
#
# Runs the "stage" command for all important targets; then zips them into the
# specified file, rooted in a directory of the same name as the zipfile.
#
# For instance: ./build overview-server.zip will create overview-server.zip
# with all its contents in an "overview-server/" directory. It will also create
# overview-server.tar.gz.
#
# The resulting zipfiles are only for experts.
