5# SYNOPSIS

7#   AX_BOOST_IOSTREAMS
8#
9# DESCRIPTION
10#
11#   Test for IOStreams 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_IOSTREAMS_LIB)
18#
19#   And sets:
20#
21#     HAVE_BOOST_IOSTREAMS
