--clean-option=--selectors-merge-mode:ie8 and to switch on advanced use

Outputs a v3 sourcemap to the filename (or output filename.map)

adds this path onto the sourcemap filename and less file paths

Sets sourcemap base path, defaults to current working directory.

--source-map-less-inline puts the less files into the map instead of referencing them

puts the map (and any less files) into the output css file

the complete url and filename put in the less file

-rp, --rootpath=URL
Set rootpath for url rewriting in relative imports and urls. Works with or without
the relative-urls option.

-ru, --relative-urls
re-write relative urls to the base less file.

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.
