+Test weave support for SWIG wrapped objects.
+
+This example requires that one has weave installed.  Weave is
+distributed as part of SciPy (http://www.scipy.org).  More information
+on Weave may be had from here:
+
+ http://www.scipy.org/documentation/weave
+
+As of November 22, 2004, this only works with weave from CVS.  If
+there is a more recent release of SciPy after this data, it should
+work fine.
