I'm pretty sure there a reference to it in some of the compare docs
or code in the files/shared_cyclic_ptr directory.

Yes. It requires declaration of a single static variable for each
class that's garbage collected. It looks like this:
ip_descriptor_of<test_subj>
ip_descriptor_of<test_subj>
::c_mk_descriptor
;
The c_mk_descriptor default CTOR creates a descriptor for test_subj.
This descriptor is accessed with:
bridge_stk_proxiterator::ip_descriptor const& subj_desc
= ip_descriptor_of<test_subj>::the_descriptor()
The iterator over smart pointers contained within an object of type,
test_subj, is created as follows:
test_subj a_subj;
bridge_stk_proxiterator subj_proxiter(subj_desc, &a_subj);
subj_proxiter iterates over all the shared_cyclic_ptr's and (hopefully
in the near future) all the unshared_cyclic_ptrs contained within
a_subj.
