[issue9253] argparse: optional subparsers

[Vincent Driessen]

Vincent Driessen <vincent at datafox.nl> added the comment:

Actually, this is a rather common concept. Broadly used tools like for example Git use this kind of subcommand handling.

This command shows all remotes:
   git remote            (i.e. is like git remote list)

Showing/removing remotes is done using subsubcommands:
   git remote show [...]
   git remote rm [...]

That, in combination with the explicit design goal that "[argparse] isn't dogmatic about what your command line interface should look like" should be enough reason to be wanting this, in my humble opinion.
