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