Parameters

The CommandManager used to create the subcommand.

commandName  String

The name of the nested subcommand, or if none was specified.

possibleMatches  ImmutableArrayString

If commandName was a prefix alias of more than one command, provides an array of the possible command names and aliases. Otherwise, this parameter is an empty array.

The base class implementation writes an error message if commandName is not , and usage help with a list of all nested subcommands. If possibleMatches is not empty, it will write a message listing the matching commands instead.
