Title says it all. Is this Less option:
http://lesscss.org/usage/#command-line-usage-source-map-map-inline
Available via grunt-contrib-less, or some other plugin? I'm not hopeful since it does not seem be mentioned anywhere in the grunt-contrib-less docs.
To be clear, I don't want grunt to output a separate map file, I'd like the mapping information to appear inline, in the primary output CSS file.
