       --derives-from vendor
              Exits with 0 if the current vendor distribution is a derivative of vendor, otherwise exits with 1.  It  uses

              never.

       DPKG_NLS
              If  set,  it  will  be  used  to  decide  whether  to  activate  Native  Language  Support,  also  known  as
              internationalization (or i18n) support (since dpkg 1.19.0).  The accepted values are: 0 and 1 (default).
