// The behaviour of the Take-methods of this class is a little non-standard, as it

// transfers ownership of the pointer owned by a CAppInfoReader derived object

// to the caller. This means that this function is only designed to be called once.

// Doing things this way provides a small performance optimisation by enabling the caller

// to delete it's stored pointer, and replace it with one returned by this function,

// instead of having to copy the object (copying could be expensive for the methods

// of this class that need to return arrays).
