80<p>A naive implementation of roughly a subset of the std::tr1::shared_ptr spec. </p>
81<p>Really just roughly - it ignores memory exceptions, for example; also note I didn't read the spec.</p>
82<p>The standard template would naturally be preferable, <b>if</b> it was included in the standard libraries of all supported compilers - but as of 2009, that's still a problem... </p>
