/// \brief Library configuration file
/// \details <tt>config_ver.h</tt> provides defines for library and compiler
///  versions.
/// \details <tt>config.h</tt> was split into components in May 2019 to better
///  integrate with Autoconf and its feature tests. The splitting occurred so
///  users could continue to include <tt>config.h</tt> while allowing Autoconf
///  to write new <tt>config_asm.h</tt> and new <tt>config_cxx.h</tt> using
///  its feature tests.
/// \note You should include <tt>config.h</tt> rather than <tt>config_ver.h</tt>
///  directly.
