+"""Simple example to show how to use weave.inline on SWIG2 wrapped
+objects.  SWIG2 refers to SWIG versions >= 1.3.
+
+To run this example you must build the trivial SWIG2 extension called
+swig2_ext.  To do this you need to do something like this::
+
+ $ swig -c++ -python -I. -o swig2_ext_wrap.cxx swig2_ext.i
+
+ $ g++ -Wall -O2 -I/usr/include/python2.3 -fPIC -I. -c \
+   -o swig2_ext_wrap.os swig2_ext_wrap.cxx
+
+ $ g++ -shared -o _swig2_ext.so swig2_ext_wrap.os \
+   -L/usr/lib/python2.3/config
+
+The files swig2_ext.i and swig2_ext.h are included in the same
+directory that contains this file.
+
+Note that weave's SWIG2 support works fine whether SWIG_COBJECT_TYPES
+are used or not.
