 # Python support
 ################################################################################
 
-# Hack:
-# protoc generated files contain imports like:
-#   "from google.protobuf.xxx import yyy"
-# However, the sources files of the python runtime are not directly under
-# "google/protobuf" (they are under python/google/protobuf).  We workaround
-# this by copying runtime source files into the desired location to workaround
-# the import issue. Ideally py_library should support something similiar to the
-# "include" attribute in cc_library to inject the PYTHON_PATH for all libraries
-# that depend on the target.
-#
-# If you use python protobuf as a third_party library in your bazel managed
-# project:
-# 1) Please import the whole package to //google/protobuf in your
-# project. Otherwise, bazel disallows generated files out of the current
-# package, thus we won't be able to copy protobuf runtime files into
-# //google/protobuf/.
-# 2) The runtime also requires "six" for Python2/3 compatibility, please see the
-# WORKSPACE file and bind "six" to your workspace as well.

-// 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.
-//
-// 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"
