   8 # The `cxxstd` feature specifies the version of the C++ Standard Language to
   9 # build with. All the official versions of the standard since "98" are
  10 # included: `98`, `03`, `11`, `14`, and `17`. It is also possible to
  11 # specify using the experimental, work in progress, `latest` version. Some
  12 # compilers specified intermediate versions for the experimental versions
  13 # leading up to the released standard version. Those are included following
  14 # the GNU nomenclature as `0x`, `1y`, `1z`, and `2a`. And depending on the
  15 # compiler `latest` would map to one of those.
  16 #
  17 # NOTE: This is an `optional` feature. Hence when not specified the compiler
  18 # default behaviour is used.
  19 #
  20 # NOTE: Please consult the toolset specific documentation for which `cxxstd`
  21 # is supported.

  27 # The cxxstd:dialet subfeature indicates if a non-standard dialect should be
  28 # used. These usually have either/or extensions or platform specific
  29 # functionality. Not specifying the dialect will default to 'iso'. Which will
  30 # attempt to use ISO C++ Standard conformance to the best of the compiler's
  31 # ability.
