I've changed the names of some types in proto to bring it in line with 
conventions established in <functional> and Boost.MPL. This should 
affect just about everybody currently using proto. In particular:

proto::multiply           ->   proto::multiplies
proto::divide             ->   proto::divides
proto::add                ->   proto::plus
proto::subtract           ->   proto::minus
proto::equal              ->   proto::equal_to
proto::not_equal          ->   proto::not_equal_to
proto::unary_plus         ->   proto::posit
proto::unary_minus        ->   proto::negate
proto::unary_star         ->   proto::dereference
proto::multiply_assign    ->   proto::multiplies_assign
proto::divide_assign      ->   proto::divides_assign
proto::add_assign         ->   proto::plus_assign
proto::subtract_assign    ->   proto::minus_assign

The corresponding tag types have also changed accordingly. For the 
complete list of tags, see:
<http://boost.cvs.sourceforge.net/boost/boost/boost/xpressive/proto/tags.hpp?view=markup>

The docs, tests and examples have been updated to reflect the new names. 
Get the latest from CVS, or from proto.zip in the Vault.
