Hello. How to use version in dub?
https://dlang.org/spec/version.html
"The version level and version identifier can be set on the 
command line by the -version"

I tried everything but noting.

In SDL syntax, either at the top level, in a configuration, 
or build type:

```
versions "something" "other"
```

To be more clear: When using dub you need to put this in the 
dub file, dub.sdl or dub.json. If you want to be able to 
choose from the command line, use a configuration:

```
configuration "something" {
    versions "something"
}
```

Then you can do:
```
dub build -c=something
```

How can this be the official solution?

It should be as easy as dub build -v "something"

Thanks for the replies. I think definitely we need a better 
documentation of this at least. It seems to have more than one 
way to do.

I tried this at first:
```
dub build -version=USE_SDL

    Error Error processing arguments: Can't parse string: bool 
should be case->> insensitive 'true' or 'false'
      Run 'dub help' for usage information.
```

Dub seems to understand my 'version' argument, but this has not 
in the help section.

And in this documentation we have more than one way to declare 
versions:
https://dub.pm/package-format-json.html#configurations

1. { "versions": ["PrintfDebugging"] }

2. like out friend said in configuration
    {
        "name": "somepackage",
        "configurations": [
                {
                        "name": "glut-app",
                        "targetType": "executable",
                        "versions": ["GlutApp"]
                }
        ]
    }

The -c argument refers to config build.
Maybe I'm confusing with package version.
But my thoughts about dub is that we need to have the best 
documentation as we can to provide a good understanding for 
newcomers in D language.
