   5 # SYNOPSIS
   6 #
   7 #   AX_BOOST_DATE_TIME
   8 #
   9 # DESCRIPTION
  10 #
  11 #   Test for Date_Time library from the Boost C++ libraries. The macro
  12 #   requires a preceding call to AX_BOOST_BASE. Further documentation is
  13 #   available at <http://randspringer.de/boost/index.html>.
  14 #
  15 #   This macro calls:
  16 #
  17 #     AC_SUBST(BOOST_DATE_TIME_LIB)
  18 #
  19 #   And sets:
  20 #
  21 #     HAVE_BOOST_DATE_TIME
