"""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.
