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.
