I didn't know an implicit subcommand was allowed. That would work,
although it does mean that you can't build a pyz from a directory
"info" without explicitly using the create subcommand.

I think I'm going to go with "python -m zipapp foo.pyz --info" (And an
-o option for the target, mandatory when the source is a pyz file, and
--python for the interpreter). It's not set in stone yet, so if anyone
objects, there's still time to change my mind.
