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