Documentation in this section is not optimal. It is spread out, and not 
very clear. In this case:


      Flags and the Meta-Object System

The Q_DECLARE_FLAGS <qflags.html#Q_DECLARE_FLAGS>() macro does not 
expose the flags to the meta-object system, so they cannot be used by Qt 
Script or edited in Qt Designer. To make the flags available for these 
purposes, the Q_FLAGS <qobject.html#Q_FLAGS>() macro must be used:

 Q_FLAGS(Options)

"Must be used"? Where? How? In a header, or in the implementation? Does 
this expand to anything, or is it supposed to be trigger moc somehow? 
And, more importantly in my case, not a word about stuff like namespaces.

Anybody any suggestions for the right incantation that I need to chant?

André
