#!/bin/bash
#---help---
# Usage: setup-build-chroot
#
# This script sets up a DCSS server build chroot, and alters the dgamelaunch
# configuration to use it for compilation.
#
# The source and chroot directories are hard-coded:
# - Config is assumed to be at: /home/crawl-dev/
# - A new build chroot is assumed to be at: /home/crawl-dev/build-chroot/
#
# It will run these steps, in order:
# - bind-mount the existing crawl-build directory into the chroot
# - add a fstab entry to do that automatically
# - patch `dgamelaunch-config/crawl-git.conf` to build via the chroot
# - install required packages
#---help---
