Running OSX 10.11, yarn v0.15.1. node v6.7.0
When running yarn help config, the output contains access as the command title, instead of config.

I had a look through the codebase, and it seems that buildSubCommands is being passed the right name, so this may be fixed and not released yet.
I've checked it locally. There is no longer an issue. Npm package need to be updated.
node bin/yarn.js help config
Usage: yarn config [set|get|delete|list] [flags]
This has been fixed.
Thanks @deecewan for the issue and @yupkey for the follow up :heart:
