Shared libraries are typically versioned as <major>.<minor>.<patch>, and the
semantics of these are tied to ABI/API compatibility. That is, every ABI
change has to be accounted for by an increment in the major version number.
That is how these links above as well as the embedded sonames are supposed
to work.

Boost right now seems to equate library versions and release versions, which
certainly adds to the confusion. Then, the name '1.33' somehow suggests
two levels of versions, while really there is only one (by the way: why do
you carry the '1.' around ? Do you expect a 'release 2' at some point ? If
so, in what way would such a release be different from an upgrade from
1.32 to 1.33, say ?)
