persistence : current state, and plans for future ?

back in October 2000 I started a thread about saving/loading objects 
à-la python's pickle,
and then discovered the boost project 'persistence' .

Now the time has come for me to save/load my nested structures ( 
including some tree<vector<vector> > ..), so I will definitely use 
persistence.

the files in the vault are dated November 2000, 
but are'nt there any private version with bits of update ?
If so, could it be uploaded somewhere in the vault, as 'alpha 
version' or some other explicit name..

Anyway, at current state, when I run persistence_demo:
abort (core dumped)  ./persistence_demo.exe

This is not really great, 
it could scare people that tries the library so as to see whether or 
not it is usable..

And it's a pity, since persistence is in fact pretty much usable.
This problem simply comes from :

void load_file(Container & cont, const std::string & filename)
{  // .....
   file.exceptions(std::ios::failbit|std::ios::badbit);

And, in the reader,  end_sequence calls check_for, who does
      is >> std::ws;
so it tries to eat whiteSpaces until EOF, raising excepton..

I added '654321' at the end of the file, and it was enough to make 
everything work nicely (since it stops is>>ws to reach EOF )
save_file : 
   //....
  save(w, std::string(typeid(Container).name()));
  save(w, cont); save(w, 654321);
But of course, other solutions are possible, like using some 
try/catch blocks.

Since I am about to use persistence, I will be playing with it a bit.
Does the author Jens Maurer plan to release it for review ?
Are there some points that are missing, or absolutely need fixing 
before review ?
