Export Namespace to Package

Hello Folks,

I have a set of classes inside a namespace of my image, which I have
implemented interactively on the shell.

Is it possible to file out all the classes in this namespace into a
package with a single command?

Ideally, the development workflow I'd like to have would be something
like this:

- Run the gst command.
- On the gst shell, create a namespace and implement a few classes
interactively.
- Export the namespace into a package on the file system.
- Save the image
- Exit the gst shell.
- Commit this package into git.

Thanks,
- Quenio
