I'm afraid a simplified explanation like that might give the impression that
the same properties can be set both for the context and for a 
particular graphical object, which of course is completely wrong.
Also, \override by default sets a property for a particular type
of object within the current context, so the concept of contexts
is important also for \override.

See the NEWS in the documentation for version 2.8. The information from 
the NEWS file is in the process of being incorporated into the manual.
