+// Before you touch the protocol files, you need to be aware of a breaking change
+// that occurred between firmware versions 1.7.3->1.8.0 (Model One) and 2.0.10->
+// 2.1.0 (Model T). The Ethereum address representation was changed from the 20
+// byte binary blob to a 42 byte hex string. The upstream protocol buffer files
+// only support the new format, so blindly pulling in a new spec will break old
+// devices!
+//
+// The Trezor devs had the foresight to add the string version as a new message
+// code instead of replacing the binary one. This means that the proto file can
+// actually define both the old and the new versions as optional. Please ensure
+// that you add back the old addresses everywhere (to avoid name clash. use the
+// addressBin and addressHex names).
+//
+// If in doubt, reach out to @karalabe.
+
+// To regenerate the protocol files in this package:
+//   - Download the latest protoc https://github.com/protocolbuffers/protobuf/releases
+//   - Build with the usual `./configure && make` and ensure it's on your $PATH
+//   - Delete all the .proto and .pb.go files, pull in fresh ones from Trezor
+//   - Grab the latest Go plugin `go get -u github.com/golang/protobuf/protoc-gen-go`

+// Options
+
+// Each of the definitions above may have "options" attached.  These are
+// just annotations which may cause code to be generated slightly differently
+// or may contain hints for code that manipulates protocol messages.
+//
+// Clients may define custom options as extensions of the *Options messages.
+// These extensions may not yet be known at parsing time, so the parser cannot
+// store the values in them.  Instead it stores them in a field in the *Options
+// message called uninterpreted_option. This field must have the same name
+// across all *Options messages. We then use this field to populate the
+// extensions when we build a descriptor, at which point all protos have been
+// parsed and so all extensions are known.
+//
+// Extension numbers for custom options may be chosen as follows:
+// * For options which will only be used within a single application or
+//   organization, or for experimental options, use field numbers 50000
+//   through 99999.  It is up to you to ensure that you do not use the
+//   same number for multiple options.
+// * For options which will be published and used publicly by multiple
+//   independent entities, e-mail protobuf-global-extension-registry@google.com
+//   to reserve extension numbers. Simply provide your project name (e.g.
+//   Objective-C plugin) and your project website (if available) -- there's no
+//   need to explain how you intend to use them. Usually you only need one
+//   extension number. You can declare multiple options with only one extension
+//   number by putting them in a sub-message. See the Custom Options section of
+//   the docs for examples:
+//   https://developers.google.com/protocol-buffers/docs/proto#options
+//   If this turns out to be popular, a web service will be set up

+  //   extend block (possibly containing multiple extension definitions) will
+  //   have an outer location whose path refers to the "extensions" repeated
+  //   field without an index.

+  //   example, the "extendee" of an extension declaration appears at the
+  //   beginning of the "extend" block and is shared by all extensions within
+  //   the block.

+  //   does not mean that it is a descendent.  For example, a "group" defines
+  //   both a type and a field in a single declaration.  Thus, the locations
+  //   corresponding to the type and field and their components will overlap.
