Fine. I'll #include new source in serialization as well so we'll all be in
the same page.

Question. Does this not mean that this if an application includes both the
serialization package as well as the program options package that some
linkers will fail to links with a duplicate symbol message?

I would also like to see

1. The documentation page and test moved to a neutral spot.
2. Could you examine my version and your version and reconcile any
differences.  Given Rene's observations, I made a pass and fixed the issues
he mentioned.  It's a could of changes but they are small and make things
much more transparent and reliable.  I've also tested them on a variety of
compilers and feel much better about it.
