+// hcl is a package for decoding HCL into usable Go structures.
+//
+// hcl input can come in either pure HCL format or JSON format.
+// It can be parsed into an AST, and then decoded into a structure,
+// or it can be decoded directly from a string into a structure.
+//
+// If you choose to parse HCL into a raw AST, the benefit is that you
+// can write custom visitor implementations to implement custom
+// semantic checks. By default, HCL does not perform any semantic
+// checks.
