The Boost1.59 page at
http://www.boost.org/users/history/version_1_59_0.html
  under 'Compilers Tested' section, contains an entry for Sun( Oracle 
Solaris Studio).

This needs modification for the upcoming Boost 1.60 release for which I 
would like to submit a PR.

I looked at https://github.com/boostorg/website but not sure if this is 
the correct repository.

Could someone please point me as to where I need to submit the PR?

Thanks,

Aparna
