       -O0, -O1, -O2
              Set  the  parser's optimization level. The lower the number, the less nodes it will
              create in the tree. This could matter for debugging, or if you want to  access  the
              individual nodes in the tree.

       --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.
