kurz/command/command.go

/*
The command package provides the command structure for kurz.

Each command is implemented in its own file: the main command.go file only
contains information for the root command, its flags, and helpers.

Command files are expected to contain the following, for a command "foo"

	- the command itself, as a *command.Cobra instance, named FooCommand
	- the command flag variables, named fooSomething. Always prefix by the command name to avoid name conflicts
	- a init() function which will bind the flags to the command, and the command itself to other commands.
	- optional:
	  - for commands usable without a subcommand, the command callable, as fooCommand(c *cobra.Command, args []string).
	  - commands needing subcommands do not need a callable

First-level commands bind to kurz, other commands may bind to the other FooCommand variables.
