+# 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.
