on the National Semi Web site i was checking out their 
Simple Switchers and lo and behold!

sample schematic and PCB in Protel format!

i think this is the first time i have ever seen that

the files were amusing though:

the SCH:
the schematic was saved in a state with all the objects selected
one of the (5 or 6) parts had no titles for the part fields
it was generally ugly

the PCB:
no components, no holes, no nets
the TO268-7 SMD power device was made from FREE FILLS

it was basically a square of copper carved up so you could lay SMD parts
across the right places 
it was actually pretty clever because it hardly mattered which
particular parts you were using, one size fits all
