+Nanopb is a small code-size Protocol Buffers implementation in ansi C. It is
+especially suitable for use in microcontrollers, but fits any memory
+restricted system.
+
+Homepage: http://kapsi.fi/~jpa/nanopb/
+
+
+
+
+Using the nanopb library
+========================
+To use the nanopb library, you need to do two things:
+
+1) Compile your .proto files for nanopb, using protoc.
+2) Include pb_encode.c and pb_decode.c in your project.
+
+The easiest way to get started is to study the project in "examples/simple".
+It contains a Makefile, which should work directly under most Linux systems.
+However, for any other kind of build system, see the manual steps in
+README.txt in that folder.
+
+
+
+Using the Protocol Buffers compiler (protoc)
+============================================
+The nanopb generator is implemented as a plugin for the Google's own protoc
+compiler. This has the advantage that there is no need to reimplement the
+basic parsing of .proto files. However, it does mean that you need the
+Google's protobuf library in order to run the generator.
+
+If you have downloaded a binary package for nanopb (either Windows or Linux
+version), the 'protoc' binary is included in the 'generator-bin' folder. In
+this case, you are ready to go. Simply run this command:
+
+    generator-bin/protoc --nanopb_out=. myprotocol.proto
+
+However, if you are using a git checkout or a plain source distribution, you
+need to provide your own version of protoc and the Google's protobuf library.
+On Linux, the necessary packages are protobuf-compiler and python-protobuf.
+On Windows, you can either build Google's protobuf library from source or use
+one of the binary distributions of it. In either case, if you use a separate
+protoc, you need to manually give the path to nanopb generator:
+
+    protoc --plugin=protoc-gen-nanopb=nanopb/generator/protoc-gen-nanopb ...
+
+
+
+Running the tests
+=================
+If you want to perform further development of the nanopb core, or to verify
+its functionality using your compiler and platform, you'll want to run the
+test suite. The build rules for the test suite are implemented using Scons,
+so you need to have that installed. To run the tests:
+
+    cd tests
+    scons
+
+This will show the progress of various test cases. If the output does not
+end in an error, the test cases were successful.

+
+// 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.
+//   Object-C plugin) and your porject 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:
+//   http://code.google.com/apis/protocolbuffers/docs/proto.html#options

+  //   [g,h)  [ 4, 0, 2, 0, 3 ]  The number (1).
+  //
+  // Notes:
+  // - A location may refer to a repeated field itself (i.e. not to any
+  //   particular index within it).  This is used whenever a set of elements are
+  //   logically enclosed in a single code segment.  For example, an entire
+  //   extend block (possibly containing multiple extension definitions) will
+  //   have an outer location whose path refers to the "extensions" repeated
+  //   field without an index.
+  // - Multiple locations may have the same path.  This happens when a single
+  //   logical declaration is spread out across multiple places.  The most
+  //   obvious example is the "extend" block again -- there may be multiple
+  //   extend blocks in the same scope, each of which will have the same path.
+  // - A location's span is not always a subset of its parent's span.  For
+  //   example, the "extendee" of an extension declaration appears at the
+  //   beginning of the "extend" block and is shared by all extensions within
+  //   the block.
+  // - Just because a location's span is a subset of some other location's span
+  //   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.
+  // - Code which tries to interpret locations should probably be designed to
+  //   ignore those that it doesn't understand, as more types of locations could
+  //   be recorded in the future.

+    //       .field(7)         // 2, 7
+    //       .name()           // 1

+Scons Builder for nanopb .proto definitions.

+application, the path to nanopb root directory has to be defined:
