#!/usr/bin/env bash
#
# Build a Keybase DMG with hdiutil, no external tools.
#
# The Finder layout (icon positions, window size, background image) lives in
# a pre-built .DS_Store template checked in at packaging/desktop/dmg/DSStore,
# originally harvested from an appdmg-built release. The template's background
# alias embeds the volume name and background path, so "Keybase App",
# ".background/Background.png", and the icon filenames must stay in sync with
# it. To change the layout: mount a rw DMG, arrange it in Finder, and copy the
# volume's .DS_Store back over the template.
