I'm trying to localise my program, and I have created a resource bundle and started to adjust the messages. It works fine, except for the help subcommand main description. I can't get it to change the default 'Display help information about the specified command'. I thought it was the key 'help.usage.header', but that has no effect.

The keys 'helpCommand.help' and 'helpCommand.command' work fine.

Any ideas?
