Usage: lessc [options] sources [destination]

 -h, --help            Print help (this message) and exit.
 -s, --silent          Suppress output of error messages.
 -v, --version         Print version number and exit.
 -x, --compress        Compress output by removing some whitespaces.
 --include-path=PATHS  Set include paths. Separated by `:'. Use `;' on Windows.
 --strict-imports      Force evaluation of imports.
 -sm=on|off            Turn on or off strict math, where in strict mode, math
 --strict-math=on|off  requires brackets. This option may default to on and then
                       be removed in the future.
 -su=on|off            Allow mixed units, e.g. 1px+1em or 1px*1px which have units
 --strict-units=on|off that cannot be represented.
 -ru, --relative-urls  re-write relative urls to the base less file.
 -rp, --rootpath=URL   Set rootpath for url rewriting in relative imports and urls.
                       Works with or without the relative-urls option.
 -w, --watch           Watch input files for changes.
