The requirements are at,
but that isn't literal text. If you want to use the text that I did then
put this in every source file:

// distribute this software is granted provided this copyright notice appears

You could wrap your uses of the allocator and string interface with
function objects or other such callbacks. But I don't see why you
need to use the same allocator for temporary storage as for the
output string.
