# This is a partial python port of nsinstall.
# It's intended to be used when there's no natively compile nsinstall
# available, and doesn't intend to be fully equivalent.
# Its major use is for l10n repackaging on systems that don't have
# a full build environment set up.
# The basic limitation is, it doesn't even try to link and ignores
# all related options.
