-# SYNOPSIS
-#
-#   AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
-#
-# DESCRIPTION
-#
-#   Test for the Boost C++ headers of a particular version (or newer)
-#
-#   If no path to the installed boost library is given the macro searchs
-#   under /usr, /usr/local, /opt, /opt/local and /opt/homebrew and evaluates
-#   the $BOOST_ROOT environment variable. Further documentation is available
-#   at <http://randspringer.de/boost/index.html>.
-#
-#   This macro calls:
-#
-#     AC_SUBST(BOOST_CPPFLAGS)
-#
-#   And sets:
-#
-#     HAVE_BOOST
-#
-#   Note that this macro has been modified compared to upstream.
