compilerconfig.json and compilerconfig.json.defaults documentation

[SergeVDev]

Hello and Happy New Year!

Where can I read about compilerconfig.json and compilerconfig.json.defaults parameters meaning?

In fact, my .min.css breaks layout (just .css, generated from a .less file, works well) and I suspect it's encoding (BOM) or something, but I don't get what does every line mean:

    "less": {
      "autoPrefix": "",
      "cssComb": "none",
      "ieCompat": false,
      "math": null,
      "strictMath": false,
      "strictUnits": false,
      "relativeUrls": true,
      "rootPath": "",
      "sourceMapRoot": "",
      "sourceMapBasePath": "",
      "sourceMap": false
    },

  "minifiers": {
    "css": {
      "enabled": true,
      "termSemicolons": true,
      "gzip": false
    },

Also, there is a parameter named noBOM, but jut for handlebars. There is no one for LESS?
