# Jeff McCune <mccune.jeff@gmail.com>
# Mac OS X Package Installer which handles .pkg and .mpkg
# bundles inside an Apple Disk Image.
#
# Motivation: DMG files provide a true HFS file system
# and are easier to manage and .pkg bundles.
#
# Note: the 'apple' Provider checks for the package name
# in /L/Receipts. Since we install multiple pkg's from a single
# source, we treat the source .pkg.dmg file as the package name.
# As a result, we store installed .pkg.dmg file names
# in /var/db/.puppet_pkgdmg_installed_<name>
# require 'ruby-debug'
# Debugger.start
