Turn on or off strict math, where in strict mode, math
requires brackets. This option may default to on and then be removed in the future.
Allow mixed units, e.g. 1px+1em or 1px*1px which have units
that cannot be represented.
--global-var='VAR=VALUE' Defines a variable that can be referenced by the file.
--modify-var='VAR=VALUE' Modifies a variable already declared in the file.

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

-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.
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.
Be verbose.
