Optionally scan tutorials directory recursively

I do not want to have a directory of tutorials. I need to have the
tutorials distributed throughout the project. I have one in each
"package" folders. My project have multiples "packages" each one maintained by different developers. These packages have a tutorial "{package_name}-tutorial.md" at its own folder. Then in the documentation I need to refer to these tutorials.
So now using " -u ./ -U" jsdoc scan recursively the root folder to index tutorials.
(I know that if these tutorials have the same name only the first one will be used)
This is the only line needed, but the rest is indented because are long.
