There has been some debate about what *should* be done. Many people have
strong feelings about it, but there appears to be no objective standard we
can use to decide.

However, I should note that using #include "..." for boost is a relatively
recent practice in the scheme of things. I think type_traits are only that
way now because Aleksey made the change when he repackaged that library. I
am afraid that a proliferation of different practices within boost is
eventually going to cause us a major problem, since "" vs. <> matters to
some tools.

Go to http://aspn.activestate.com/ASPN/Mail/Browse/Threaded/boost/ and
search for "angle include"
