                        [featureName] can be any one of these:

                        autoprefixer        filterOptimiser     normalizeUrl
                        calc                filterPlugins       orderedValues
                        colormin            functionOptimiser   reduceIdents
                        convertValues       mergeIdents         singleCharset
                        core                mergeLonghand       styleCache
                        discardComments     mergeRules          svgo
                        discardDuplicates   minifyFontValues    uniqueSelectors

    --safe              Disable advanced optimisations that are not always safe.
                        Currently, this disables custom identifier reduction,
                        z-index rebasing, unused at-rule removal & conversion
                        between absolute length values.


    --version,    -v    Outputs the version number.

    --help,       -h    Outputs this help screen.
```
