The <info>generate:bundle</info> command helps you generates new bundles.

By default, the command interacts with the developer to tweak the generation.
Any passed option will be used as a default value for the interaction
(<comment>--namespace</comment> is the only one needed if you follow the
conventions):

<info>php app/console generate:bundle --namespace=Acme/BlogBundle</info>

Note that you can use <comment>/</comment> instead of <comment>\\</comment> for the namespace delimiter to avoid any
problem.

If you want to disable any user interaction, use <comment>--no-interaction</comment> but don't forget to pass all needed options:

<info>php app/console generate:bundle --namespace=Acme/BlogBundle --dir=src [--bundle-name=...] --no-interaction</info>

Note that the bundle namespace must end with "Bundle".
