Darshan Sen	568a4d2a63	Use variadic templates to get rid of manual overloads in construct.hpp There is no need to write the overloads manually and limiting our users to a max of 10 arguments when we can forward universal references to the constructors.

Edward Diener	b90488068a	[skip ci] Add "cxxstd" json field. The "cxxstd" json field is being added to each Boost library's meta json information for libraries in order to specify the minumum C++ standard compilation level. The value of this field matches one of the values for 'cxxstd' in Boost.Build. The purpose of doing this is to provide information for the Boost website documentation for each library which will specify the minimum C++ standard compilation that an end-user must employ in order to use the particular library. This will aid end-users who want to know if they can successfully use a Boost library based on their C++ compiler's compilation level, without having to search the library's documentation to find this out.	2021-01-20 13:08:07 -05:00
