libboost-doc binary package in Ubuntu Xenial s390x

 The Boost web site provides free, peer-reviewed, portable C++ source
 libraries. The emphasis is on libraries which work well with the C++
 Standard Library. One goal is to establish "existing practice" and
 provide reference implementations so that the Boost libraries are
 suitable for eventual standardization. Some of the libraries have
 already been proposed for inclusion in the C++ Standards Committee's
 upcoming C++ Standard Library Technical Report.
 .
 This is documentation for the boost libraries in HTML format.
 Some pages point to header files provided in the corresponding -dev package,
 so it is suggested to install the latter as well.
 .
 This package is a dependency package, which depends on Debian's default
 Boost version (currently 1.58).
