I am curious, I know Expat is an XML parser or something like that,
but if those libraries that use it do not use features like DTD
verification and such, why not just make an XML parser in Spirit2.1,
it is certainly proven to be just about faster then anything else yet
tested.

Also, I have never used an MPI system, but from quick perusing of what
MPI based systems look like, why does Boost.MPI create a full MPI
system instead of just create a glue on top of it?  Especially since
all the MPI system I see seem to cost a rather ridiculous amounts of
money?  I am probably missing something about the MPI standard though,
but I do not see what from a quick reading that would warrant such
costs I see.
