-'''
-Scons Builder for nanopb .proto definitions.
-
-This tool will locate the nanopb generator and use it to generate .pb.c and
-.pb.h files from the .proto files.
-
-Basic example
--------------
-# Build myproto.pb.c and myproto.pb.h from myproto.proto
-myproto = env.NanopbProto("myproto")
-
-# Link nanopb core to the program
-env.Append(CPPPATH = "$NANOB")
-myprog = env.Program(["myprog.c", myproto, "$NANOPB/pb_encode.c", "$NANOPB/pb_decode.c"])
-
-Configuration options
----------------------
-Normally, this script is used in the test environment of nanopb and it locates
-the nanopb generator by a relative path. If this script is used in another
-application, the path to nanopb root directory has to be defined:
-
-env.SetDefault(NANOPB = "path/to/nanopb")
-
-Additionally, the path to protoc and the options to give to protoc can be
-defined manually:
-
-env.SetDefault(PROTOC = "path/to/protoc")
-env.SetDefault(PROTOCFLAGS = "--plugin=protoc-gen-nanopb=path/to/protoc-gen-nanopb")
