The current version of examples is here:

https://svn.boost.org/svn/boost/trunk/libs/geometry/example_extensions/gis/projections/

and look at tests here, where you can see how to use EPSG:

https://svn.boost.org/svn/boost/trunk/libs/geometry/test_extensions/gis/projections/

If you need to find EPSG or PROJ.4 definitions, "+proj ...", check
http://spatialreference.org/

I can provide you with more complete example but not earlier than in 2-3 days.
Let me know if you still need it.
