              E.g.  the  clean  css  plugin  is  called less-plugin-clean-css once installed (npm
              install less-plugin-clean-css), use either with  --plugin=less-plugin-clean-css  or
              just        --clean-css        specify        options        afterwards        e.g.

       -------------------------- Deprecated ----------------

       -sm=on|off

       --strict-math=on|off

       --line-numbers=TYPE
              Outputs filename and line numbers.  TYPE  can  be  either  'comments',  which  will
              output   the  debug  info  within  comments,  'mediaquery'  that  will  output  the
              information within a fake media query which is compatible with the SASS format, and
              'all' which will do both.

       -x, --compress
              Compresses  output  by removing some whitespaces.  We recommend you use a dedicated
              minifer like less-plugin-clean-css
