Hi Nils,

The serialization code you can find in the sandbox is probably
of little use to you, since it requires deep modifications in
Boost.Serialization itself that are not part of the official

An obvious way to serialize flyweight<T> is to simply serialize
their underlying T values (you'll also need to use reset_object_address
if T of the tracked kind.) This has the disadvantage that when T is
not tracked thatyou'll get many repetitions of the saved values, and
thus big archives. The sandbox code tries to remedy this, but alas
at the expense of modifications to Boost.Serialization, as mentioned
above. I couldn't find a better solution, but I'd be delighted if
someone finds it. Count on me for help/guidance if you decide
to tackle the task.
