  5# SYNOPSIS
  6#
  7#   AX_BOOST_PROGRAM_OPTIONS
  8#
  9# DESCRIPTION
 10#
 11#   Test for program options 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_PROGRAM_OPTIONS_LIB)
 18#
 19#   And sets:
 20#
 21#     HAVE_BOOST_PROGRAM_OPTIONS
