// Run must be implemented by any plugin because it is part of the
// plugin interface defined by the core CLI.
//
// Run(....) is the entry point when the core CLI is invoking a command defined
// by a plugin. The first parameter, plugin.CliConnection, is a struct that can
// be used to invoke cli commands. The second paramter, args, is a slice of
// strings. args[0] will be the name of the command, and will be followed by
// any additional arguments a cli user typed in.
//
// Any error handling should be handled with the plugin itself (this means printing
// user facing errors). The CLI will exit 0 if the plugin exits 0 and will exit
// 1 should the plugin exits nonzero.

// GetMetadata() returns a PluginMetadata struct. The first field, Name,
// determines the name of the plugin which should generally be without spaces.
// If there are spaces in the name a user will need to properly quote the name
// during uninstall otherwise the name will be treated as seperate arguments.
// The second value is a slice of Command structs. Our slice only contains one
// Command Struct, but could contain any number of them. The first field Name
// defines the command `cf basic-plugin-command` once installed into the CLI. The
// second field, HelpText, is used by the core CLI to display help information
// to the user in the core commands `cf help`, `cf`, or `cf -h`.

You can’t perform that action at this time.
