+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")
