Hi Gavin,

Just to be clear, is it just "using namespace boost;" I need to worry about,
or do I also need to strip out entries like "using namespace
boost::filesystem;"?

"using namespace xxx" is probably a bad idea in any [if not all] case[s], if the namespace is lengthy [as they tend to be in Boost], it would be better to define a (distinctive) namespace alias.
