7 /// \details <tt>config.h</tt> was split into components in May 2019 to better
8 /// integrate with Autoconf and its feature tests. The splitting occurred so
9 /// users could continue to include <tt>config.h</tt> while allowing Autoconf
10 /// to write new <tt>config_asm.h</tt> and new <tt>config_cxx.h</tt> using
11 /// its feature tests.
