+# SYNOPSIS
+#
+#   AX_BOOST_FILESYSTEM
+#
+# DESCRIPTION
+#
+#   Test for Filesystem library from the Boost C++ libraries. The macro
+#   requires a preceding call to AX_BOOST_BASE. 
+#
+#   This macro calls:
+#
+#     AC_SUBST(BOOST_FILESYSTEM_LIB)
+#
+#   And sets:
+#
+#     HAVE_BOOST_FILESYSTEM
