#!/bin/bash
#
# This script builds minidump_stackwalk binaries from the Google Breakpad
# source for all of the operating systems that we run Firefox tests on:
# Linux x86, Linux x86-64, Windows x86, OS X x86-64.
#
# It expects to be run in the luser/breakpad-builder:0.7 Docker image and
# needs access to the relengapiproxy to download internal tooltool files.

# This is a pain to support properly with gclient.
