Hey!
Just send a pull request to GitHub repo. ;)
I have a lot of work recently, but I should finish today a Contribution guide, which should clarify everything about patches and collaboration.
There is a reason for this, bundles in /src directory are application specific, they won't be reused in any other app.
The contain customized Entities, needed services, configuration and templates ( they override the ones in /vendor/bundles ).
You probably didn't notice that all Sandbox bundles extend the main Sylius bundles, which have their own repos and are the true power.
For example SandboxAssortmentBundle extends SyliusAssortmentBundle, mainly to modify the templates and organize all related code.
For the main Sylius app I plan to have only one SyliusCoreBundle to tie all other togather, as the templates overriding will be handled by theming bundle.
Bundle inheritance is well described in Symfony2 docs I think.
I also will write a documentation article about Architectural concepts behind Sylius bundles.
Thanks a lot for the patches, It really makes me happy to see poeple helping on Sylius.
Please sent 2 separate pull requests. : )
Bests,
Paweł.
