end

#slides ⇒ Object

Notes re filesets config and slides: All PresentationApps need the same slides but different configs (including templates, etc.)

So: there need to be TWO valises:

1) The slides valise - including slidesets that might get included - this one is common between all Apps

2) The config valise - there should be a “common” base to this, and a role specific variation. Built special, because the /viewer app should allow for config in the root of the project etc, while the /presenter version should require special config (since I’m assuming a boring presentation view)
