lessc-make is a front-end to less-js with some extra options for easier usage with Makefiles.
It does not yet include all options that the original lessc supports.
$ lessc-make --help
Compile .less into .css with dependency tracking for Make.
Usage: lessc-make [options] source dest
lessc-make [options] --no-css source
Options:
--help, -h Show this help.
--verbose, -v Show verbose output.
--silent, -s Do not show warning from the less compiler.
--include-dir, -I FOLDER Add an include path for the less compiler. May be specified multiple times.
--no-css Do not write the compiled CSS.
Source map generation:
--source-map PATH Generate a source map file.
--source-map-inline Generate an in-line source map.
--source-map-include-source Include the sources in the source map.
--source-map-root PATH Root path of the less sources, relative to the location of the source map (calculated automatically if not specified).
--source-map-base PATH Base path to use when forming relative paths to the source map in generated CSS output (defaults to the CSS output directory).
--source-map-url URL URL or path where the source map can be retrieved, relative to the output CSS.
Dependency tracking:
--depends, -d PATH Write dependency information to the given file. If the path is omitted, it will be created next to the output CSS file.
--depends-phony, -p Add a phony target for each dependency to prevent errors if the dependency is deleted.
--depends-target, -t TARGET Manually specify the target for the generated dependencies. Needed if CSS output is written to stdout.
