Type: Object
Default: {}
Context for directives used in your preprocessed files. The default context consists of the current user environment variables. Custom context is merged with process.env.
Type: String
Base directory for included files. By default, the path to included files is relative to the file currently being processed.
Type: String
Override the file extension. This determines what regular expressions are used for comments. You may wish to do this if you are using a custom extension or need to force a particular comment syntax (for example, to allow HTML-style comments in .php files).
