Actually, this doesn't fix anything.

Since changes to binary archives where checked in, any archive classes
derived from this archive are no longer guarenteed to work. Portable
archive is such a class. In fact, the original intent of the example
was to illustrate how to make a new archive by deriving from an
existing one. The changes to binary archive now render this example
incorrect and misleading. I would not now recommend using binary
archive as a base class for this reason.

The new version of portable archive - recently
checked into the trunk - fixes this by not being based on binary archive
any more. It's been tested to create portable archives - but its still
being checked out.

Unfortunately, this was not discovered until late in the developement cycle
and its not a trivial fix. It ripples through the documentation. And of
course, we need a new example to illustrate how best to do this. And
this entails making a good example, and test and corresponding
documentation. So its not a trivial fix.

The only fix at this point is to update the Introduction section to
include the information related above.
