OK, you are right.  I missed the fact that this was an example for totally 
self-contained recipe (it's like the gumstix example).  However this isn't 
the usual case and 'for dummies' should IMHO document the most common case 
in a way it would be acceptable to this list.

Given the amount of variations found in the repository I would refer 
interested persons to read the source and provide a link to the user 
manual.  The manual is actually quite good :-)
