+# SYNOPSIS
+#
+# AX_BOOST_PROCESS
+#
+# DESCRIPTION
+#
+# Test for Process 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_PROCESS_LIB)
+#
+# And sets:
+#
+# HAVE_BOOST_PROCESS
