+// URL that describes the type of the serialized message.
+//
+// Protobuf library provides support to pack/unpack Any values in the form
+// of utility functions or additional generated methods of the Any type.
+//
+// Example 1: Pack and unpack a message in C++.
+//
+//     Foo foo = ...;
+//     Any any;
+//     any.PackFrom(foo);
+//     ...
+//     if (any.UnpackTo(&foo)) {
+//       ...
+//     }
+//
+// Example 2: Pack and unpack a message in Java.
+//
+//     Foo foo = ...;
+//     Any any = Any.pack(foo);
+//     ...
+//     if (any.is(Foo.class)) {
+//       foo = any.unpack(Foo.class);
+//     }
+//
+//  Example 3: Pack and unpack a message in Python.
+//
+//     foo = Foo(...)
+//     any = Any()
+//     any.Pack(foo)
+//     ...
+//     if any.Is(Foo.DESCRIPTOR):
+//       any.Unpack(foo)
+//       ...
+//
+// The pack methods provided by protobuf library will by default use
+// 'type.googleapis.com/full.type.name' as the type URL and the unpack
+// methods only use the fully qualified type name after the last '/'
+// in the type URL, for example "foo.bar.com/x/y.z" will yield type
+// name "y.z".
+//
+//
+// JSON
+// ====
+// The JSON representation of an `Any` value uses the regular
+// representation of the deserialized, embedded message, with an
+// additional field `@type` which contains the type URL. Example:
+//
+//     package google.profile;
+//     message Person {
+//       string first_name = 1;
+//       string last_name = 2;
+//     }
+//
+//     {
+//       "@type": "type.googleapis.com/google.profile.Person",
+//       "firstName": <string>,
+//       "lastName": <string>
+//     }
+//
+// If the embedded message type is well-known and has a custom JSON
+// representation, that representation will be embedded adding a field
+// `value` which holds the custom JSON in addition to the `@type`
+// field. Example (for message [google.protobuf.Duration][]):
+//
+//     {
+//       "@type": "type.googleapis.com/google.protobuf.Duration",
+//       "value": "1.212s"
+//     }
+//
+type Any struct {
+	// A URL/resource name whose content describes the type of the
+	// serialized protocol buffer message.
+	//
+	// For URLs which use the scheme `http`, `https`, or no scheme, the
+	// following restrictions and interpretations apply:
+	//
+	// * If no scheme is provided, `https` is assumed.
+	// * The last segment of the URL's path must represent the fully
+	//   qualified name of the type (as in `path/google.protobuf.Duration`).
+	//   The name should be in a canonical form (e.g., leading "." is
+	//   not accepted).
+	// * An HTTP GET on the URL must yield a [google.protobuf.Type][]
+	//   value in binary format, or produce an error.
+	// * Applications are allowed to cache lookup results based on the
+	//   URL, or have them precompiled into a binary to avoid any
+	//   lookup. Therefore, binary compatibility needs to be preserved
+	//   on changes to types. (Use versioned type names to manage
+	//   breaking changes.)

+// `FieldMask` represents a set of symbolic field paths, for example:
+//
+//     paths: "f.a"
+//     paths: "f.b.d"
+//
+// Here `f` represents a field in some root message, `a` and `b`
+// fields in the message found in `f`, and `d` a field found in the
+// message in `f.b`.
+//
+// Field masks are used to specify a subset of fields that should be
+// returned by a get operation or modified by an update operation.
+// Field masks also have a custom JSON encoding (see below).
+//
+// # Field Masks in Projections
+//
+// When used in the context of a projection, a response message or
+// sub-message is filtered by the API to only contain those fields as
+// specified in the mask. For example, if the mask in the previous
+// example is applied to a response message as follows:
+//
+//     f {
+//       a : 22
+//       b {
+//         d : 1
+//         x : 2
+//       }
+//       y : 13
+//     }
+//     z: 8
+//
+// The result will not contain specific values for fields x,y and z
+// (their value will be set to the default, and omitted in proto text
+// output):
+//
+//
+//     f {
+//       a : 22
+//       b {
+//         d : 1
+//       }
+//     }
+//
+// A repeated field is not allowed except at the last position of a
+// field mask.
+//
+// If a FieldMask object is not present in a get operation, the
+// operation applies to all fields (as if a FieldMask of all fields
+// had been specified).
+//
+// Note that a field mask does not necessarily apply to the
+// top-level response message. In case of a REST get operation, the
+// field mask applies directly to the response, but in case of a REST
+// list operation, the mask instead applies to each individual message
+// in the returned resource list. In case of a REST custom method,
+// other definitions may be used. Where the mask applies will be
+// clearly documented together with its declaration in the API.  In
+// any case, the effect on the returned resource/resources is required
+// behavior for APIs.
+//
+// # Field Masks in Update Operations
+//
+// A field mask in update operations specifies which fields of the
+// targeted resource are going to be updated. The API is required
+// to only change the values of the fields as specified in the mask
+// and leave the others untouched. If a resource is passed in to
+// describe the updated values, the API ignores the values of all
+// fields not covered by the mask.
+//
+// If a repeated field is specified for an update operation, the existing
+// repeated values in the target resource will be overwritten by the new values.
+// Note that a repeated field is only allowed in the last position of a field
+// mask.
+//
+// If a sub-message is specified in the last position of the field mask for an
+// update operation, then the existing sub-message in the target resource is
+// overwritten. Given the target message:
+//
+//     f {
+//       b {
+//         d : 1
+//         x : 2
+//       }
+//       c : 1
+//     }
+//
+// And an update message:
+//
+//     f {
+//       b {
+//         d : 10
+//       }
+//     }
+//
+// then if the field mask is:
+//
+//  paths: "f.b"
+//
+// then the result will be:
+//
+//     f {
+//       b {
+//         d : 10
+//       }
+//       c : 1
+//     }
+//
+// However, if the update mask was:
+//
+//  paths: "f.b.d"
+//
+// then the result would be:
+//
+//     f {
+//       b {
+//         d : 10
+//         x : 2
+//       }
+//       c : 1
+//     }
+//
+// In order to reset a field's value to the default, the field must
+// be in the mask and set to the default value in the provided resource.
+// Hence, in order to reset all fields of a resource, provide a default
+// instance of the resource and set all fields in the mask, or do
+// not provide a mask as described below.
+//
+// If a field mask is not present on update, the operation applies to
+// all fields (as if a field mask of all fields has been specified).
+// Note that in the presence of schema evolution, this may mean that
+// fields the client does not know and has therefore not filled into
+// the request will be reset to their default. If this is unwanted
+// behavior, a specific service may require a client to always specify
+// a field mask, producing an error if not.
+//
+// As with get operations, the location of the resource which
+// describes the updated values in the request message depends on the
+// operation kind. In any case, the effect of the field mask is
+// required to be honored by the API.
+//
+// ## Considerations for HTTP REST
+//
+// The HTTP kind of an update operation which uses a field mask must
+// be set to PATCH instead of PUT in order to satisfy HTTP semantics
+// (PUT must only be used for full updates).
+//
+// # JSON Encoding of Field Masks
+//
+// In JSON, a field mask is encoded as a single string where paths are
+// separated by a comma. Fields name in each path are converted
+// to/from lower-camel naming conventions.
+//
+// As an example, consider the following message declarations:
+//
+//     message Profile {
+//       User user = 1;
+//       Photo photo = 2;
+//     }
+//     message User {
+//       string display_name = 1;
+//       string address = 2;
+//     }
+//
+// In proto a field mask for `Profile` may look as such:
+//
+//     mask {
+//       paths: "user.display_name"
+//       paths: "photo"
+//     }
+//
+// In JSON, the same mask is represented as below:
+//
+//     {
+//       mask: "user.displayName,photo"
+//     }
+//
+// # Field Masks and Oneof Fields
+//
+// Field masks treat fields in oneofs just as regular fields. Consider the
+// following message:
+//
+//     message SampleMessage {
+//       oneof test_oneof {
+//         string name = 4;
+//         SubMessage sub_message = 9;
+//       }
+//     }
+//
+// The field mask can be:
+//
+//     mask {
+//       paths: "name"
+//     }
+//
+// Or:
+//
+//     mask {
+//       paths: "sub_message"
+//     }
+//
+// Note that oneof type names ("test_oneof" in this case) cannot be used in
+// paths.

-package conf
-
-// The format supported is less restrictive than today's formats.
-// Supports mixed Arrays [], nested Maps {}, multiple comment types (# and //)
-// Also supports key value assigments using '=' or ':' or whiteSpace()
-//   e.g. foo = 2, foo : 2, foo 2
-// maps can be assigned with no key separator as well
-// semicolons as value terminators in key/value assignments are optional
