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.
