// Look at "example/fruit.proto" not this file

// this file is actually used by autogenpb

// here are some docs, but probably it's just easier to run
// autogenpb on this file and see what gets autogenerated
// in this directory. All autogenerated files are named *.pb.go

// the 'uuid' standard at the end is an experiment
// establish a way to identify arbitrary .pb files

// You can generate Marshal & Unmarshal for any struct (message) you want
// You can generate SortBy and Append functions ONLY FOR 'repeated <message>'
// Also, those structs must be defined in the same file
// Additionally, you must use `autogenpb:mutex` on the parent struct. 
// The autogenerated code requires a RW mutex and autogenpb will insert it into the struct

// below are the actual structs autogen uses
// autogen parses the .proto file and then store the information
// it needs in these protobuf files, then it processes the
// protobuf files to write out *.sort.pb.go and *.marshal.pb.go files
