autogenpb tries to generate a sort.pb.go file for a protobuf
Install with:
go install go.wit.com/apps/autogenpb@latest
More information at:
https://go.wit.com/
The protobuf is assumed to have a 'standard' format.
That is the .proto file:
* only defines one thing and it's the same name as the file
* uses the concept of 'plural' (like ruby on rails)
This means, the file should be "apples.proto" and inside
have 'message Apple' and 'message Apples'
The "message Apples" should have a repeated Apple apples
There is an example in the code:
go-clone go.wit.com/apps/autogenpb
`

func (args) Version() string {
return "go-clone " + VERSION + " Built on " + BUILDTIME
