Shared_ptr has to mention Boost, but as the source of ourimplementation,
not std::tr1::shared_ptr in general.  I see no need for any other part
to refer to Boost, nor to mention the hash_xxx containers unless it is
simply to say "the unordered_xxx containers are suitable replacements
for the non-standard hash_xxx containers in the SGI STL" (with a link to
ext/howto.html)  i.e. mention them as redundant, not as the inspiration
for the new classes.
