devel/boost: what's proper shared library version?

[Alexander Churanov]

Folks,

Could somebody officially and explicitly tell me, how to assign shared
library versions for new boost ports?

I see following possibilities:

1) Use boost release version as shared library version.
    This is safe and recommended by boost.

2) Use some other approach.
    I do not see alternatives, so please give your advice if you are
aginst option #1.

Please, remember that boost.org does not examine binary compatibility
of their libraries, because this is nearly impossible to do for all
platforms and compilers. They also easily may break compatibility even
when fixing a bug due to heavy use of metaprogramming.

Sincerely,
Alexander Churanov,
maintainer of devel/boost
