# SYNOPSIS

#

#   AX_BOOST_PROGRAM_OPTIONS

#

# DESCRIPTION

#

#   Test for program options library from the Boost C++ libraries. The macro

#   requires a preceding call to AX_BOOST_BASE. Further documentation is

#   available at <http://randspringer.de/boost/index.html>.

#

#   This macro calls:

#

#     AC_SUBST(BOOST_PROGRAM_OPTIONS_LIB)

#

#   And sets:

#

#     HAVE_BOOST_PROGRAM_OPTIONS

#

# LAST MODIFICATION
