# Zypper is a wrapper class around the zypper package manager
#
# Zypper offers access to the system-wide zypper environment, but it also allows
# for running zypper in an isolated environment using 'Zypper.isolated'.
# That way Machinery can safely add repositories and download packages without
# polluting the host.
