.start(options = {}) ⇒ Object

Starts Boson by loading configured libraries. If no default libraries are specified in the config, it will load up all detected libraries. Options:

:libraries

Array of libraries to load.

:verbose

Boolean to be verbose about libraries loading. Default is true.

:no_defaults

Boolean or :all which turns off loading default libraries. If set to true, effects loading user’s console default libraries. If set to :all, effects all libraries including boson’s. Default is false.

:autoload_libraries

Boolean which makes any command execution easier. It redefines method_missing on Boson.main_object so that commands with unloaded libraries are automatically loaded. Default is false.
