Remove LESS // comments on compile

Question

Is it possible to configure LESS to remove \"// comments\" when it compiles via JS?

I want to remove them from the outputted less file.

Answer 1

2015-July update: when trying the -x option as the other answers suggested, I got this warning:

The compress option has been deprecated. We recommend you use a dedicated css minifier, for instance see less-plugin-clean-css.

You can install the plugin with

npm install -g less-plugin-clean-css

Then run lessc with the --clean-css argument.
