Hi,
> Why is this important?

I am trying to compile http://geometrylibrary.geodan.nl/02__linestring__example_8cpp-example.html. (in general , what is the boost version used for these examples?)
( vs2010, BOOST 1.49)
It could not find:
#include <boost/geometry/geometries/cartesian2d.hpp<http://geometrylibrary.geodan.nl/cartesian2d_8hpp.html>>
// Optional includes to handle c-arrays as points, std::vectors as linestrings
#include <boost/geometry/geometries/adapted/c_array_cartesian.hpp<http://geometrylibrary.geodan.nl/c__array__cartesian_8hpp.html>>
#include <boost/geometry/geometries/adapted/std_as_linestring.hpp<http://geometrylibrary.geodan.nl/std__as__linestring_8hpp.html>>
I got a work around so the above (include)problem is solved.

But it  doesn't know:
intersection_inserter

A local search shows that intersection_inserter
exists only in doc directories.

//nothing found

Q1.What is the first release to have intersection_inserter.hpp?

Q2.
By  reading  a  ChangeSet  can I figure out the release when those changes appeared?

Example: I  searched "intersection_inserter" and found:
https://svn.boost.org/trac/boost/changeset/67473
where is says:
algorithms/intersection_inserter.hpp was added.

Don't know this by head - have to figure it out (about the same way as you would do it - so that must be in changeset 67473 indeed). The headerfile is newer than the source itself, there always was an intersection_inserter algorithm from one of the first previews.

Why is this important?
