Retrieve or set a configuration value
$ bundle config NAME [VALUE]
Retrieves or sets a configuration value. If only parameter is provided, retrieve the value. If two parameters are provided, replace the existing value with the newly provided one. By default, setting a configuration value sets it for all projects on the machine. If a global setting is superceded by local configuration, this command will show the current value, as well as any superceded values and where they were specified.
