// The gohaml package contains a HAML parser similar to the one found at http://www.haml-lang.com.

/*
Engine provides the template interpretation functionality to convert a HAML template into its
corresponding tag-based representation.

Available options are:
  engine.Options["autoclose"] = true|false, default true

The Options field contains the values to modify the way that the engine produces the markup.

The Indentation field contains the string used by the engine to perform indentation.

The IncludeCallback field contains the callback invoked by the gohaml engine to process other files
included through the %include extension.
